"There was too much focus on what they were going to do in their next game.
"But this year it's about us. By having a good season, we will become the champions.

United have been in fine form in the Premier League this season, winning 18 out of a possible 22 matches and going unbeaten in 10 games since their 1-0 defeat to Norwich on November 17.
