"Now we are entering the decisive moments of the season," said the midfielder.
"To be champions is difficult but not impossible. We are developing a sensational run and we have not given up on anything.
"Our match against United is key. A victory at Old Trafford would open up our chances for the end of season and it would be a big blow in the Premier League for United.
"Our objective is to go to Manchester and win and it would not surprise me if we did. We are playing our best football of the season."
