Former Chelsea defender Glen Johnson is convinced Romelu Lukaku will prove a huge success at Stamford Bridge.

The Blues completed a £97.5million transfer to sign Lukaku, 28, from Inter Milan last week and he is set to make his second debut for the club at Arsenal on Sunday.

"Lukaku is going to score loads of goals and he'll cause all teams a lot of problems," Johnson told SBK Sportsbook.

"He's almost the modern upgrade on Olivier Giroud. People used to moan when Giroud played, but I don't think people realised how good he was for that side.

"Lukaku is the same, but quicker and more powerful. He's a great addition for that style of play. It wouldn't surprise me if he had a field day against Arsenal.

"At Chelsea the first time, it didn't really work, but he now knows the league. He's obviously a more mature player now.

"If he didn't think he was capable then I'm sure he wouldn't have gone back. He's tactically better than he was and his game awareness has improved big time. This time around he can make it work."
