Man Utd captain Fernandes: We must go to Porto to win

United need to bounce back after Sunday's home collapse to Tottenham and the midweek home draw against Twente.

"It's a side that always does really well in Europe, we have to be aware of that," Fernandes told MUTV.

"It's a team that has a great spirit,   improving a lot in the last few games, even if they lost the last game in the Europa League.

"It is a team that has been improving under their new manager," he added, referring to Vitor Bruno.

"We expect a really difficult game there, but we go there to win because it’s everything that we have to think about."
