Manchester United striker Javier Hernandez feels their Europa League defeat to Ajax is a good wake-up call for their Premier League hopes.
With the Premier League title set to be decided by the finest of margins, the Mexican striker insists they must not slip up again.
He said: "We cannot afford any draws or losses like that in the league.
"We need to learn from the Ajax game because it is not a good feeling, but we have to look forward and keep working."
