In Michu, Swansea have the man currently challenging Robin van Persie for the Premier League's Golden Boot prize and Evans has already seen enough to recognise a stern examination awaits at the Liberty Stadium.
"I have been really impressed," said Evans.
"We watched a couple of videos on them I have seen them quite a bit on TV. The football they play is very good.
"When they changed their manager, maybe people thought they might change their style. But, although they are a little bit more direct, largely they stuck to it.
"They are still a side that scores a lot of goals.
"We know it is going to be a tough game but we know how to play against them and it is a game we are looking forward to."
