Chelsea youngster Nathan Ake has said the help of new signing Diego Costa, along with Fernando Torres will make him a better player.
In an interview with the Chelsea website, Ake has been talking about how facing the club's main strikers in training can help him develop as a player, given the 19-year-old plays in defensive roles and in central midfield.
He said: "It’s difficult because they are so strong, both of them are top strikers but testing myself against such good players will only help me improve my own game."
Costa is seen as the man to produce the goods in front of goal for Chelsea this season after playing a pivotal role in Atletico Madrid's run to the La Liga title and the Champions League final. He scored a total of 64 goals from 138 games for Atleti - with 36 of those coming from the 51 games he played last season.
Torres is a man whose future looks a little uncertain having been linked with a move back to Atletico having had an underwhelming spell at Stamford Bridge despite showing flashes of his quality on occasions. Even those flashes can give the best of defenders some trouble and young players will inevitably learn from going up against him.
Ake wants to try and impress against the top class players in the Chelsea squad, in order for Jose Mourinho to take notice, and possibly consider him to be part of the first team squad for the coming season.
The Dutchman added: "In these friendlies all the younger players are looking to perform and impress the manager, if we do that hopefully we will be involved with the squad this season. I’m working hard every day in training, the games are coming and it’s important that I do my best."
