West Ham midfielder Nolberto Solano has expressed his sympathy for Peruvian compatriot Claudio Pizarro.
Pizarro has had limited opportunities to impress at Chelsea since Jose Mourinho's departure and has not started a Premier League game since 12th January.
Didier Drobga and Salomon Kalou have since returned from the Africa Cup of Nations and Pizarro is once again likely to be left out when Chelsea line up against West Ham on Saturday.
Solano believes Pizarro is capable of making an impact in the Premier League but accepts that competition for places is fierce at Stamford Bridge.
He said: "It is difficult for Claudio as Mourinho signed him and he then had to leave the club.
"He is a good player but it is difficult when you play up front and if you don't score goals.
"Drogba is very important in the system they play and they bought Anelka so it is a big challenge for him to try and improve more and, if he has the chances, to take them.
"Especially at a club like Chelsea, you need to perform well. At the moment it is difficult for him to get into the team."
Solano is looking forward to the clash against Chelsea but admits it will be difficult for West Ham to take anything from the game.
"Chelsea is always a hard game," he said. "At the moment we know how desperate they are for three points, especially after they lost the Carling Cup.
"They are desperate to finish in the top four to qualify for the UEFA Champions League, or even win the league. For Chelsea, if they do not win any trophies, it will be difficult for them."
