Thomas Tuchel admitted Chelsea's 1-0 defeat against Arsenal was a "wake-up call" after Emile Smith Rowe punished Jorginho's blunder to dent the Blues' bid to finish in the Premier League's top four. Midfielder Jorginho was guilty of a woefully misplaced back-pass that ended with Gunners youngster Smith Rowe slotting home early in the first half at Stamford Bridge. Tuchel's side were bereft of quality in the final third as they succumbed to only a third defeat in their 26 matches in all competitions. Chelsea remain in fourth place, but their bid to qualify for next season's Champions League via a top four finish is now on a knife edge. They sit six points clear of fifth placed West Ham, who have a game in hand, and seven ahead of sixth placed Liverpool, who could be the biggest threat with two games in hand. "I don't know how Arsenal would have scored if we didn't give it to them. We scored more or less an own goal, a total gift," Tuchel said. 

"We were not sharp enough, not the same energy as usual. I'm not happy with what I saw. "It was maybe too many changes from the last match and I take full responsibility for that. Maybe it's the last wake-up call for all of us." Chelsea's tepid display was hardly ideal preparation for their attempt to win the first trophy of Tuchel's reign in Saturday's FA Cup final against Leicester at Wembley. "I felt it a little bit coming in training and I'm a bit unlucky that it's proven today on the pitch," Tuchel said. "We had some good results so we have to cope with a loss."
