Just for interest, really, seeing as Olympians are no doubt going to be put against opponents of.... limited... threat.

Which current British fighter had the most challenging debut?

I'll suggest Matt Skelton- he fought a guy who had won his last three (out of 4) by Knockout!

Haye had Tony Booth

Darren Barker boxed Howard Clarke, who, although he was by then a typical Nobby Nobbs loser, did fight Fernando Vargas for the IBF title

Nathan King.
