Anthony Joshua v Wladimir Klitschko

With so many unknowns, this fight is incredibly difficult to call.

Joshua is completely unproven at the top level, with his most impressive win to date coming against Dillian Whyte. He was wobbled in that fight, though, and question marks remain over the IBF champion’s chin.

Klitschko, meanwhile, looked scared to throw punches against Tyson Fury and has a history of being knocked out himself.

That defeat is enough to make Joshua the favourite, and backing him at to knock the Ukrainian out is the safest way to go in this fight.

Klitschko is a master of clinching and taking fights into the later rounds with his jab, though, and the fact that Joshua has never been beyond the seventh is a major concern.

The 41-year-old to win by decision – priced at – is therefore worth a punt.

Luke Campbell v Darleys Perez

Joshua is not the only Olympic champion on Saturday’s card.

Campbell – who took bantamweight gold in 2012 – looks poised to move into title contention with a win over former WBA king Perez.

The Colombian lost his belt to Anthony Crolla in November 2015, and has won just one and drawn two of his last four fights.

He has only ever beaten one opponent from outside of South America – Uzbekistani journeyman Bahodir Mamadjonov.

Perez is durable, however, and while Campbell has stopped 13 of his 17 opponents he does not have tremendous punching power.

At , he’s good value to win by decision.

Scott Quigg v Viorel Simion

Quigg’s push to get back into super-bantamweight title contention should continue with a comfortable win over Simion.

The Romanian lost a unanimous decision to Lee Selby in his only fight against top-class opposition, while Quigg – a former world champion – has only lost a split to 2016 Fighter of the Year Carl Frampton.

The Englishman has a fine record of 24 knockouts in 32 wins, but took nine rounds to put away the overmatched Jose Cayetano in his first fight since losing to Frampton.

Working with new trainer Freddie Roach, he is likely to be working on some new things, so it’s worth backing him to win by decision at .

Katie Taylor v Nina Meinke

Meinke – undefeated in five professional fights – is a real step up in competition for Taylor.

But the German has never fought outside of her home country, and is yet to face a fighter anywhere near as good as the Olympic gold medallist.

Taylor has completely outclassed her four previous opponents, and should ultimately come through this test.

She hasn’t displayed much knockout power as a professional, though, with her two stoppage wins to date coming in the third and fifth rounds.

So a points victory for the Olympian, priced at , is the right bet.

Lawrence Okolie v Russ Henshaw

This will be an easy win for Okolie in his third professional fight, having beaten both of his last two opponents inside the first round.

The Olympian will surely make light work of Russ Henshaw, who has lost four of his last five fights, twice by knockout.

Another first-round KO win for Okolie is a safe bet at .
