Carl Froch thinks a sell-out Wembley crowd could see the "best and last" of Wladimir Klitschko when he steps into the ring to face Anthony Joshua next month.

Klitschko has not fought since his sensational defeat to Tyson Fury back in November 2015, but the 41-year-old makes his comeback in a heavyweight title bout against Joshua on April 29.

Former heavyweight king Klitschko is 14 years Joshua's senior, but ex-super-middleweight world champion Froch is expecting big things from the veteran Ukrainian in front of a partisan crowd of 90,000.

"We know Klitschko is an ageing fighter but with age comes wisdom and the experience he's got," Froch told Sky Sports.

"He's had 68 fights and he was unbeaten in 10 years as a heavyweight up until he faced Tyson Fury and that was an awkward, torrid night for him.

"He had problems in the background with his wife going through post-natal depression and it wasn't publicised much but if he had something else on his mind, wasn't switched on and on top of that had someone like Tyson Fury goading him, smiling and doing his weird dance for 12 rounds, he just couldn't get going.

"We may just see the best - and last - of Wladimir Klitschko.

"It's at Wembley Stadium and if he is thinking 'this is my final fight on this stage' - with 90,000 not 80,000 - and if he thinks to himself 'this is it for me, my exit card, my final fight', you know he is going to turn up.

"Klitschko is going to be at the best he can possibly be and Joshua is inexperienced. That is the only word I am going to use about Joshua because he is good, excellent, in every other department."
