Chelsea starlet Andreas Christensen insists he will remain patient for his chances in the Blues first team having only just recently stepped up from the youth side.

The highly-rated 18-year-old centre half has been retained in the first team squad after Jose Mourinho allowed Tomas Kalas to leave for FC Cologne on a season long loan.

While his only involvement in the first team so far has been a spot on the substitutes bench in the League Cup victory over Bolton, the Chelsea manager has been keen to get the Dane working alongside his defensive stalwarts and has already advised the youngster to concentrate on his fitness.

Speaking to Danish outlet BT, Christensen said: "He asked me to focus [more] on my physique. So that is what I am doing right now."

Christensen, who left Brondby to join Chelsea's youth ranks ahead of the 2012/13 season, played in the first team during their pre-season campaign but sits behind John Terry, Gary Cahill, and Kurt Zouma in Mourinho's pecking order, with Branislav Ivanovic also an option.

But the Dane has dismissed suggestions his patience is wearing thin and insists he is more than happy with the chances to train alongside the club's seasoned veterans on a daily basis.

"Only a few months ago I was moved from Chelsea's youth squad to the first team," he said. "Yet I have only played friendly matches. My patience is not exhausted yet.

"Chelsea is a very special club. First team players are at a very high level. [Training with first team players] I still get a lot out of it. Not least John Terry who is a good teacher. The experience he has, I would benefit from."

Christensen is one of three academy players to be included in Chelsea's first team squad this season along with Nathan Ake and Lewis Baker.
