Arsenal fullback Nacho Monreal admits they've blown the title after a slow start to the season.
The Gunners face Burnley at Turf Moor aiming for an eighth consecutive Premier League win.
"We had quite a difficult start," said Monreal. "We were winning games but also losing points along the way and those points we lost earlier in the season are proving to be a problem now.
"Can we catch Chelsea? We will try. It is very difficult but we are only thinking about winning the next seven games. You never know. It is a dream but we can only win the next seven and see if they lose some games."
