Chelsea ace Didier Drogba has urged strike partner Andrei Shevchenko to become more of a team player, if he wants to be a success.
Shevchenko has struggled to live up to expectations this season and he has been in and out of the team recently.
Drogba believes the pressure placed on Shevchenko following his £30million switch from Milan last summer has not helped the Ukrainian, as he is only focused on scoring goals rather than forging a partnership in attack.
"On Shevchenko's side, I don't really sense the desire to collaborate," Drogba told The Sun.
"I think that as a big signing, he believes he is obliged to justify his transfer fee with goals at any cost. I love to share but when I give, I appreciate it when I get something back.
"That's what happened with Hernan Crespo. But let's say it is a little different this season.
"That is a real pity because everyone would have something to gain if we really worked together. I have tried to understand his position and get an explanation.
"We know we are not rivals because, unlike in the past years, there is room for two in attack this season.
"I understand it is a really difficult situation for him to handle. But you have to think of the team first."
Meanwhile, Drogba has backed Jose Mourinho in his desire to bring in new players in this month's transfer window.
Mourinho has been at loggerheads with the club's board over their failure to support his transfer plans, with the Portuguese tactician keen to bring in a new defender to ease his side's injury problems.
However, Chelsea so far have failed to make funds available to bring in a new player.
Drogba supports Mourinho's stance and insists all the players at the club are behind their manager.
"Let's get one thing clear, when Mourinho says we need new players to help us achieve our ambitions, he is talking on behalf of the whole group," added Drogba.
"All the players here feel the same way as Jose."
