Chelsea defender Baba Rahman admits he has found his first six months in English football frustrating having struggled to impose himself on the first-team at Stamford Bridge.

Rahman, 21, joined the Blues from Bundesliga side Augsburg during the summer transfer window but has made just four league appearances for the club. Despite Branislav Ivanovic and Cesar Azpilicueta having far from vintage seasons this term, the Ghana international has remained on the sidelines.

Rahman is yet to feature under new manager Guus Hiddink but remains determined to prove his worth in west London. "Of course it's frustrating for any footballer to sit in the stands and I don't want to experience that too much more," Rahman told Bild, as reported by the Guardian.

"As a young player, of course, you have to get used to such a big club and a world-class league. For me the first half of the season was pretty OK but in the second half I really want to play more. Chelsea are one of the best clubs in the world."

Rahman featured sparingly under Mourinho who admitted in October 2015 the youngster needed time to adapt because he "doesn't know what it is to play in this kind of championship."

While his opportunities under the former Blues boss were limited, Rahman isists he appreciated his time working under Mourinho. "He always gave me tips on how to improve both defensively and going forward," he said. "I liked him right from the first moment. Every player would benefit from working with him."

After their 2-0 win over Scunthorpe in the FA Cup on Sunday 10 January, Chelsea return to Premier League action on Wednesday (13 January), hosting West Brom at Stamford Bridge. A win could see Hiddink's leapfrog the Baggies into 12th place, if Southampton fail to beat Watford at home.
