FT: Chelsea 0-1 Arsenal
Chelsea boss Thomas Tuchel bemoaned his sides missed chances in their 1-0 loss to Arsenal on Wednesday night.
The Blues boss also took full responsibility for his side's home defeat after making seven changes for the London derby.
Emile Smith Rowe broke the deadlock when Jorginho made a mistake with his back pass to goalkeeper Kepa Arrizabalaga earlier in the first half.
Despite Chelsea dominating possession and hitting the woodwork twice late on, they couldn't find an equaliser as Arsenal sealed their first win at the Bridge in 10 years.
The west London club remain fourth in the English top flight on 64 points but the defeat gives their rivals hope of securing a top-four spot. They are now six points ahead of West Ham, who have a game in hand, and seven ahead of Liverpool, who have two games in hand.
Speaking to BBC Match of the Day after the defeat, Tuchel said: "The first half was OK, it was enough to lead 3-0 but we were 1-0 down because we forgot to score at the other end and then scored an own goal practically, I don't know how Arsenal would've scored if we didn't give it to them ourselves.
"We were not sharp enough, not the same energy as usual. We are responsible, I am responsible, we are all in this together so it was not enough to win the game.
"Bit angry that we had so many changes, that's on me, not so happy in the end with the line-up, but I didn't know what would happen, I didn't feel us today like I normally do and we can't expect to win games if we're not 100% in games. We didn't have a shot for almost the whole second half, then we had a big one, maybe we deserved this today, we learn something.
"I'm not happy with what I saw, I have my responsibility because I picked the line-up, but the performance was the performance."
On whether it's good to get a loss out of the way before the FA Cup final: "It's a bad thing - I don't need these things to wake up to know how hard it is, I don't need to lose to know this, we needed to wake up again together but I don't know why. Now everybody is awake again."
Chelsea right wing-back Reece James asserted when he spoke to Sky Sports: "We lost. We made a mistake which led to their goal and didn't take our chances. We only have ourselves to blame for the loss. On another day maybe the game goes differently.
"They're a good team and hard to break down. We had chances to score and put the game to bed.
"The games come thick and fast and the players come in and out. Everyone is at different fitness levels. We all put 100% in and we're going to get tired sometimes.
"It doesn't affect us in any way. We're still fighting to win very game. The loss doesn't affect us tonight.
"It's disappointing to lose but we can't take negativity into tomorrow's session."
