Arsenal right-back Hector Bellerin has urged his teammates to keep their heads up following Sunday's 1-0 defeat to Chelsea at the Emirates.
From the 18th minute, Arsene Wenger's side played with 10 men as Per Mertesacker was sent off with a straight red card after bringing down Diego Costa while he was through on goal.
Costa punished Arsenal further when he scored the only goal of the game in the 23rd minute, preventing the Gunners from returning to the summit of the Premier League table.
"It is difficult because [even though we were] playing with 10 men we thought in the second half that we wouldn't give up, and we had some chances to get a better score," Bellerin told reporters.
"It couldn't be done and it was a bit unlucky on our part. We need to keep our heads up and move onto the next game.
"We always think of [the title]. We take it game by game and when it comes to May we will see where we are."
Arsenal will switch focus to the FA Cup this weekend when they take on Burnley in the fourth round at the Emirates.
