United know that, if it is to have any chance of lifting the Premier League trophy, it has to comprehensively beat Sunderland and hope that Manchester City slip up at home to the relegation-threatened Rs.
City has won 17 of its 18 league matches at the Etihad Stadium so far this season but the Ecuador international retains hope.
He told The Sun on Sunday: “We cannot lose all hope. We must fight until the very last moment.
“If City do win it instead it will be so disappointing and the problem will be that we failed in games that theoretically were easy.
“People may think that the key was our two derby defeats this season. But they weren’t so decisive as the loss to Wigan or the incredible 4-4 draw against Everton. Never did I think we would lose two points in the final 10 minutes of that one at Old Trafford.
“If City win on Sunday I shall congratulate our rivals. But let’s hold on, there are still 90 minutes of the season to go.”Follow GOAL.COM USA on
