Enrique said: "You cannot say that any striker has made a game difficult for Martin this season. Against many different strikers this season he has had an amazing game.
"He is doing really, really well for us. He has everything. He's good in the air, he's a strong player, he's quick, he's good with the ball.
"For me, I wouldn't swap him for any centre-back in the Premier League. I know Kompany is a good centre-back too but I prefer Martin."
Skrtel has appeared 37 times for Liverpool this season.
