Arsenal boss Arsene Wenger admits Middlesbrough have given them a title boost after holding Manchester United to a 2-2 draw on Sunday.
"If they had won, I would have thought we could not (win the league) but, now, I still believe we'll do it."
Wenger continued: "We did have a dip recently, it's true. We can't deny that. But football is strange sometimes.
"It is possible we can win the last five games. Of course, I said that before the Liverpool game as well, but I said five games and one draw would make it.
"It is compulsory that we win at Old Trafford if we want to win the championship."
