The Panel: What will Terence Crawford bring to the table against Ricky Burns?

Ricky Burns is one of Britain's four world champions and he is the first this year to put his title on the line.

So Terence Crawford is the latest American to try and beat a British world champion in his own backyard. But what's he got? GLENN: Well he is a decent puncher, if not a devastating one. He should be tidy as well because he does have a good amateur record and is undefeated. He looks the sort of guy that will try and keep Ricky busy and that might be his strong point but he is still coming through and is by no means a world-class operator... yet. Also this is his first 12-rounder, which is a whole new world. One important thing for me is where he has boxed before. With all due respect, Nebraska, Pennsylvania, Knoxville and the rest are hardly big time, are they? Yes he has built his record and has maybe done it under the radar but for all the quality we have seen from him, we have never seen him at this level before. JOHNNY: He is a slick operator and I think he thinks this is a done deal already. He looks like a guy who is coming over here to dethrone Burns because of that confidence. Technically he seems to be a tidy fighter and he is going to create Ricky a lot of problems but no matter what he is thinking, he needs to produce his best performance if he is going to have a chance. His skill-set might make him the favourite and his main assets seem to be his movement and his sharpness. But he is not a big puncher and does he have the fitness and the engine to go down the distance? We'll see because he clearly looks confident. JIM: Well I was in the gym on Tuesday to take a look at the public workout and although he was only on the pads and the bag briefly, he was what everyone expects: he looks mobile, he looks smart and he looked good. In fact he looked like just the sort of opponent Ricky will not like. He prefers guys who will stand up in front of him and have a brawl, but Crawford is not going to do that. It makes it a 50-50 fight already and you can see why many people are making him the favourite. He's cute, clever and skillful and if you remember Ricky struggling and being out-boxed by Jose Gonzalez and even Raymond Beltran, you do worry. This is going to be one tough night but Crawford is no beast. He has a respectable knockout record and he can catch you cleanly, but he this is not going to be over quickly.

This is, of course, not the first time an American with a big reputation has visited these shores to take on our best, but which other which US visits stick in your mind? GLENN: The Americans always think they can walk in, take our titles and head home. Remember Oliver McCall at Wembley Stadium. Frank Bruno was supposed to be past it and we all know what happened! But the one that I remember was Marvin Hagler coming over to take on Alan Minter. I sat watching it on the box and although it turned nasty and he was bombarded with bottles - which was a disgrace - we just saw Hagler and what he was all about. He wasn't one of those loud American fighters full of himself, he was a different kettle of fish: he just came over to destroy Minter and that is what he did. He is much easier to talk to these days and I think he moved to Italy because Sugar Ray Leonard had completely psyched him out and he needed to get away. But when he came to London he's paid his dues - and more - so you expected it from him. Has Terence Crawford done that? No. JOHNNY: For me it has to be Gerald McClellan coming over to take on Nigel Benn. Forget the horrible ending because me and my wife were there and it was one of those nights you will never forget. He was the most brutal fighter I had seen, so he had this repuration that came before him - and rightly so. He had the swagger, he had that confidence that only the Americans seem to have. There was an aura about him, there really was - and don't forget that Nigel had been across the pond and taken some big scalps and earned some rare respect from them. But even then they thought their man was going to walk over him and I am sure they are saying the same thing about Crawford - and he is nowhere near as ominous as McClellan was. Lennox Lewis slowly and surely dominated the American scene but they inisted he was Canadian so whatever respect they had for him didn't last long. If this lot have done their homework and aren't over confident they have a chance. But if they think this is already in the bag, then they are in for a big surprise... JIM: The one that impressed me hugely was Donald Currie. He came over here as the world champion against Colin Jones and I had never seen anything like him before - or since! He looked from the same mould as Sugar Ray Leonard and was simply phenomenal. He blocked punches with his arms but was riding the shots at the same time, then countered, as he blocked. Soon after Lloyd Honeyghan went out there and stunned the world, but Currie was a class act. People up here in Scotland are saying Burns-Crawford is like when Howard Davis came over and I managed to hold on to my world title. He was a brilliant, brilliant fighter. He won Olympic gold, he was in that unbelievable USA team and to be honest, everyone knew I was the world champion but the Americans just thought I was keeping it warm until Howard took it away. Well they had no idea what they were up against; he didn't have any great experience and he had no Plan B. I hope this turns out to be the same problems for Crawford.
