Chelsea have made an offer for FC Tokyo striker Yoshinori Muto, according to the club president Naoki Ogane.
The 22-year-old Japanese, who has made 11 appearances for his country, scored 13 goals, and was included in the J-League's Best XI in his debut season after being handed a professional contract by FC Tokyo in 2013.
Muto has also had a very impressive start to the new season, scoring three goals in four games so far.
The youngster has caught the eye of Jose Mourinho's side, who have made an offer believed to be about £4 million for the striker, according to club president Ogane.
"It is true that Chelsea sent us an offer for Muto. It is a formal offer with conditions. They want to acquire him in the summer," said Ogane, according to the Telegraph.
Muto despite admitting that he is honoured to be approached by a big club like Chelsea, says that he has still not decided on whether he will be accepting Chelsea's offer or not.
"I have not decided yet at all. It is an honour for me to receive this offer from a great club," he said, according to the Telegraph.
Meanwhile, Chelsea defender Gary Cahill feels that the Blues will have another difficult test when they take on Premier League strugglers Queens Park Rangers this weekend.
While the Blues managed a narrow 1-0 win over Stoke City in their last Premier League fixture, QPR thrashed West Brom 4-1 on the weekend before recording a 3-3 draw against Aston Villa on Tuesday.
And Cahill admits that the Blues will be facing a tough London Derby game at Loftus Road especially with the Hoops fighting hard to remain in the Premier League next season.
"They're [QPR] fighting for their lives to stay in the league and that's dangerous for us because they will do anything to win the match. We're away and the atmosphere will be good," the former Bolton defender told Chelsea's official website.
However, the centre-back is certain that the Blues will be coming up on top on Sunday if they are focused.
"We need to go there fully focused and with the same attitude we had against Stoke. Hopefully that will be good enough to get a win."
