Jol is wary of the threat Michu poses but will not be taking Swansea for granted regardless of the Spaniard's availability.
"Michu was a player known by his manager and that always helps," he said.
"It is the same that I had with Mahamadou Diarra or Dimitar Berbatov, which helps because you know for a fact they will do well.
"He knew him and it was probably the same with Chico Flores, the centre-back. He knew him as well.
"That helps but he has scored more goals than before so the Premier League is well suited to Michu.
"Sometimes he plays in the hole as a number 10 or up front, but they have other players that can play in that position."
