Chelsea made an offer, reportedly worth £4million, for Yoshinori Muto earlier this week.
The Japan international has already scored three times in four games for FC Tokyo at the start of the new J-League season.
Jose Mourinho admitted that the signing of the left winger is taking place due to the marketing interest of signing from Japan.
He said: “In modern management you cannot close the door to a bit of commercial interests.”
The Premier League leaders’ interest was revealed before he was chosen as the Player of the Month in the JLeague.
The 22-year-old started his career as a youngster at FC Tokyo before leaving to read Economics at Keio University.
At university he kept playing football where he impressed so much that FC Tokyo offered him a professional contract.
Muto still managed to graduate from University two weeks ago despite a very busy couple of years in which he has been capped for the national team 11 times.
He scored 13 times last season and was named in the league’s team of the year.
The Japanese starlet reportedly said: “I’m honoured to receive an offer from this wonderful team, but I have not made any decision yet.”
