Kurt Okraku, the representative of Chelsea left-back Baba Rahman, says his client needs to back up, admitting that expectations for the defender must be measured as well.
Baba joined Chelsea in August after making 31 appearances for Augsburg in the German Bundesliga.
He has, however, been restricted to just nine appearances in all competitions including four English Premier League outings and three Uefa Champions League games.
“I am the player’s guardian and I know in my heart that this is his first season at the club,” Okraku told Citi FM.
“We need to be modest with our expectations. He knows he must work very hard at the club to get his opportunity.
“If he gets between 15 and 20 matches this season, I will be happy. When he signed in the summer, we knew that there would be challenges.
“We knew that there were top stars in the team and that Rahman needed to be serious with his work.”
Baba made his Chelsea debut in a 4-0 thrashing of Maccabi Tel-Aviv in the Champions League in September before earning a Premier League bow in a 2-0 home triumph over Aston Villa.
Signed by Jose Mourinho, and coupled with his struggle for regular action, there have been rumours that Baba could be headed for a loan back to Augsburg following the Portuguese coach’s sack after a run of poor results.
