Off the back of Sunday's League Cup semi-final defeat by city rivals Hibernian, Wouter Vrancken's injury-ravaged squad travelled to Switzerland in need of a shot of optimism. Instead, they shot themselves in the foot twice and were left facing an uphill battle. First, Jamie McCart scored a horror own-goal, poking past goalkeeper Beau Reus into the bottom corner under relatively little pressure. Twelve minutes later, Stephen Kingsley's attempted clearance presented Brighton Labeau with a straightforward finish to make it 2-0. Thun could have been further ahead before half-time, but Reus saved well from Nils Reichmuth. Thun - struggling domestically themselves - threatened every time they turned the ball over and a third goal came on 56 minutes as Furkan Dursun got in front of Stuart Findlay to beat Reus at the near post. Findlay headed a late consolation goal for the Tynecastle outfit, but a comeback was never on the cards. Hearts are 32nd in the 36-team table with one point, while Thun are 20th on three.

Junior Olaitan's goal - a rebound after Sam Johnstone saved his penalty - looked like condemning Celtic to a grim club record of five consecutive defeats in European competition. But Martin O'Neill's side were transformed after a triple substitution just after the hour mark, when Osmand, Duran and Colby Donovan entered the fray. Osmand and Duran scored three times between them, and Osmand also grabbed an assist in a chaotic final half hour during which Celtic came from behind to lead, and were then pegged back, before Duran won it on 87 minutes. Just 43 seconds after Osmand entered the pitch, Callum McGregor read a pass into midfield by Besiktas and pinched possession, before feeding the 20-year-old substitute. Osmand did the rest as he drove up to the edge of the box and drilled the ball low past Alexander Nubel to level the game. From there, the previously flat crowd roared into life and Celtic's intensity completely changed. Liam Scales had a header pushed over from a corner and Osmand slipped in Benjamin Nygren, who whipped a right-footed shot just over the crossbar. But Osmand was not done there, as he then teed up Duran, who stayed calm to round Nubel and slide the ball home. Then, came an unexpected twist. Orkun Kokcu wrestled momentum back for Besiktas with a belting strike from the edge of the box which flew past Johnstone. However, Celtic's response was almost instant. Kieran Tierney drove forward and scuffed his shot, but it fell for Duran to side-foot home from close range and - after a check for offside - Celtic Park went berserk. Almost cheered as loudly was Johnstone's terrific take from a Besiktas cross, which signalled the end of the game and a desperately needed Europa League win for Celtic.

Tyler Adams, Evanilson and Rayan all came on as substitutes to score as the Cherries made it four wins from four in their debut European campaign. American midfielder Adams got the equaliser soon after the break, to cancel out Ebrima Singhateh's first-half opener, when he finished well after Amine Adli had sparked a move by pouncing on a mistake from the Czech side's defence. It followed Tobias Guddal being sent off for Sparta in the first half for a second yellow card. The Cherries had to wait until nine minutes to go to get the second, Evanilson providing a superb finish from inside the area to put them ahead before Rayan scored the third with an effort from just outside the box. Bournemouth boss Rose made eight changes from their weekend win over Leeds United and the visitors struggled early on in Prague. Jonatan Braut Brunes missed a great opportunity in the opening moments before Bournemouth's Lewis Cook hit the post with a penalty following a handball from former Liverpool and Wolves defender Ki-Jana Hoever. Sparta took a deserved lead in the 35th minute after some brilliant footwork from Singhateh, who used a clever trick to beat Adam Smith and Cook in one movement before delivering a brilliant finish. The Czech side's joy was short-lived as two minutes later they were reduced to 10 men as defender Guddal was sent off for a second bookable offence, for pulling down Alvaro Rodriguez. That certainly took the momentum from the hosts and Rose opted to bring on some of his regulars as Adams was the first substitute at the interval. He had an immediate impact, with his energy reinvigorating Bournemouth, and got his goal 12 minutes after the restart. Rose then continued to make changes with Evanilson, Adrien Truffert, Marcus Tavernier and Rayan all coming off the bench as they penned in Sparta looking for the winning goal but squandered chances. But they got the important goals late on to make it seven wins in a row in all competitions.

Kamada prodded home from close range, sending the ball through goalkeeper Oliver Baumann's legs, to level for Pierre Sage's side in stoppage time. The German visitors had looked destined to win at Selhurst Park as Palace, who had Adam Wharton sent off, struggled to find a way through despite enjoying long spells of possession. Palace started the game promisingly, but Hoffenheim took the lead when Alexander Prass met a Tim Limperle cross and fired a low shot which slipped awkwardly underneath goalkeeper Dean Henderson, who should have done better. The visitors almost doubled their advantage when Andrej Kramaric connected with a volley from close range and forced Henderson to make a sharp save. Hoffenheim continued to cause problems with their direct attacking play, while Palace initially struggled to find any rhythm after falling behind. Palace began to find their feet towards the end of the first half, with some neat passing moves helping them disrupt Hoffenheim's increasingly deep defence. Prospects of avoiding defeat seemed to worsen for Palace, though, when Wharton was shown a second yellow card late on for a foul on Wouter Burger. But they continued to look for chances as they set up camp in the attacking third and eventually managed to snatch a goal and a point thanks to Japan international Kamada. A tough test awaits Palace in their next match when they host Liverpool (14:00 GMT) in their last Premier League game before the international break. They sit 18th in the table, with Sage's future coming under scrutiny.

Manager Mikel Arteta made six changes to the team that beat Liverpool in the Premier League on Sunday, with Gyokeres leading the line in place of Kai Havertz. The Swedish striker played a huge part in the opening goal when he hooked the ball behind the Slavia Prague defence for Noni Madueke to race on to and finish confidently in the ninth minute. Gyokeres added the second himself before half-time after he exchanged passes with Mikel Merino and curled an excellent finish in off the post. Slavia Prague improved after the break, and almost immediately David Raya had to produce a good save to deny Oskar Kubiak who shot from the edge of the box. Gabriel Magalhaes had to clear the ball off the line after a Mojmir Chytil header following a corner, and the home side eventually pulled one back when Wiktor Nowak scored from close range in the 90th minute. The Gunners, who had a 100% record in this stage of the competition during the last campaign, are unbeaten after their opening four games this season and are third in the table behind Paris St-Germain and Real Madrid.
