New FSV Mainz 05 striker Yoshinori Muto says regular football is the reason why he turned down the opportunity of playing for Chelsea to join the German Bundesliga side.
The 22-year-old was a £4m target for the Blues as confirmed by a spokesman for Japanese club FC Tokyo but admitted that he is not yet ready to feature in the Premier League.
"I wanted to keep my expectation realistic and play for a team that fits my level," the player is quoted as saying to Sky Sports.
"I began to want to compete at a level above. They really showed they wanted me. From the word go I'd like to focus on scoring goals."
In his career, Muto scored 25 goals in 55 games for FC Tokyo.
