LONDON (AFP) - Chelsea manager Jose Mourinho described Pedro Rodriguez as "one of the best attacking players in the world" on Friday and suggested the Spaniard might not be the club's last signing.

Pedro signed from Barcelona on Thursday, four days after left-back Baba Rahman joined from German side Augsburg.

Praising Pedro's attitude, Mourinho said the pair had helped to boost Chelsea in training following the disappointment of a 2-2 draw at home with Swansea City and a 3-0 loss at title rivals Manchester City.

"Well, we normally train very well, but I think this week we trained better than ever," said Mourinho, ahead of his side's third game of the Premier League season at West Bromwich Albion on Sunday.

"Why? Because we are not happy. I'm not happy with the results. The players are not happy with the results. We want to do better, and there is only one way: to work well, and better than ever, which we did all this week.

"New players are always welcome, so obviously I'm happy that they have come to us. This week we got a very good young left-back that we need, with potential that we believe can be developed.

"And we got one of the best attacking players in the world, a player with lots of experience and with something that I really like very, very much, which is the desire to leave a giant club, one of the best clubs in the world, a club that normally - when you are there - you don't want to leave. "For a player like him (Pedro), loved in the club, who loves the club, and he wants to leave because he wants something more for his career, that's an evident sign of ambition. He wants to play every game.

I'm really happy with these two players."
