Former Rangers players Kevin Thomson and David Weir are convinced Bayer Leverkusen ace Kai Havertz will be a huge hit at Chelsea.

Speaking ahead of Rangers' Europa League last-16 second-leg tie against Leverkusen on Thursday, Thomson backed Havertz to succeed at whichever club he moves to.

"I think that [price tag] just puts into perspective of the calibre of the team we're going to face tonight," Thomson said on BT Sport.

"He's a real top player, it's there for everyone to see and I've got no doubt if he does go into a different team in Europe, whether he ends up in the English Premier League, I'm pretty sure he will take it by storm.

"He's a real talent, I think unusual for a forward player, he'll score goals with his head but he'll also run in behind. He looks a real star."

Former Rangers defender Weir can see why the likes of Chelsea are interested in Havertz.

"He does [score different types of goals], he can play in different positions around the front areas and that's a real skill," Weir said.

"You see the goals he scores as well, they're all different types of goals.

"He scores with his head, both feet, he can score off a No 9 or he can be the No 9 himself.

"He's got real good variation in his play and you can see why the top clubs really are looking at him."
