United will be looking to respond after the weekend and, although Porto lost their Europa League opener against Norwegian side Bodo/Glimt last week, their recent results in Liga Portugal have been positive. Sunday’s 4-0 win over Arouca was their third successive domestic victory since losing to Sporting CP at the end of August.
“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, [are] improving a lot in the last few games, even if they lost the last game in the Europa League.
