Yuri Zhirkov has the blessing of his coach at CSKA Moscow to leave the club if the opportunity arises.
Reports suggest that Chelsea are set to make a move for the 25-year old in summer and his coach, former Brazilian star Zico said he will not stand in his way.
"Zhirkov is a player of such high level, he would only show all his potential playing in such a strong competition as the English Premier League," he told The Sun.
"He'd easily fit into Chelsea's first-choice team. I don't like to lose him, but I won't stop his move to London."
