But his Reds pal Dirk Kuyt insists Europe's defences have not seen the best of him yet.
The Dutch striker said: "It's true, I think he can be even better this season.
"He is only 23 and can only get better and better."
Kuyt continued: "Fernando already knows how difficult the Premier League can be - but he did really well last year. The only thing he has to be careful about is that people know him now.
"But for a player with his qualities, he is always going to be difficult to play against.
"He knows that and the defenders know that as well - and they will be afraid of him. If he stays fit he can do even better than last season."
