He told liverpoolfc.tv: "Fernando speaks a bit of English, though he's not confident enough to do interviews yet. But in the dressing room he's got a bit about him and it's always good to see a player trying to adapt and learn the language. He's a good lad. The Spanish lads are helping him settle in.
"He was magnificent at Reading. The thing about Fernando is that he's a top-class player but he works so hard for the team. You can see that. The manager obviously likes all the players to work hard and the strikers to track back - he does that extremely well, as well as his more obvious qualities.
"His goals were fantastically taken and it was a superb all-round performance.
"He's a strong lad and he proved that he can certainly cope with the physical side. He comes from a different way of playing - Spanish football is different to English football - but he's an extremely strong physical player. He has pace and attributes to help him cope with that. I'm sure he's going to be a force this year.
"I enjoy playing with a player with such blistering pace as Fernando. I'll hold the ball up and get in the box, he can run onto the loose balls and get in behind defences. I certainly think we complement each other. Fernando can win things in the air as well but the fact that he is pacy and reads the flicks helps him get in behind."
