Thomas Tuchel admits Romelu Lukaku is the type of player Chelsea were 'missing' last season after he earned the Blues a win over Zenit St Petersburg on Tuesday.
Lukaku scored his fourth goal in four matches since rejoining the West London club for £98million this summer by heading home Cesar Azpilicueta's cross in the 69th minute of the game to win 1-0 at Stamford Bridge.
Tuchel believes it is Lukaku's clinical edge that makes him a 'world-class' striker and claims the club are 'very happy to have him' considering he has scored four of his six shots on target this season.
