Brainbox Otto: I'll outsmart AJ

WALLIN READY FOR AN UPSET

- CHRIS MCKENNA

OTTO WALLIN believes brain training will help him wreck Anthony Joshua’s mind and date with Deontay Wilder.

The Swedish southpaw also questioned the Brit’s latest change in coaches.

Wallin has been brought in as a warm-up act to Joshua’s showdown with Wilder next year.

But the 33-year-old is not talking like an underdog ahead of tomorrow night’s showdown here in Saudi and reckons he will go further than when he came close to beating Tyson Fury in 2019. ‘The Gypsy King’ may have inadvertently helped to give Wallin the belief to take down his British rival.

The former prison officer at a psychiatric hospital for criminals has been using a sports psychologist to ensure he has the mental strength to achieve his dreams.

Wallin has been working with Ake Fjellstrom for most of his professional career and believes he will be key to taking down AJ and wrecking the British heavyweight’s career.
