The Swedish contender produced a career-best performance last weekend, sealing a dominant points win over Dominic Breazeale, who had only previously been beaten by Joshua and Deontay Wilder.
Wallin emerged with credit from his only setback, a battling points loss to Fury in September 2019, and Salita believes the 30-year-old is back in contention with the division’s best fighters.
“Otto did a great job on Saturday night establishing himself as the top, elite heavyweight in the world,” Salita told Sky Sports.
“Otto is on the same level as Joshua and Fury. The scary part is that he keeps getting better.”
Joshua says he is ‘ready’ to finalise an undisputed world title fight against Fury in June, with a variety of countries still being considered to stage the blockbuster battle.
Otto versus the Joshua-Fury winner would be one of the biggest fights to make,” said Salita.
“We are going to keep Otto busy. He is on his way to a world title and mega heavyweight fights.”
The New York-based southpaw, who has previously sparred with Joshua, had recently told Sky Sports that he expects Fury to defeat his British rival.
“I think AJ versus Fury is the fight to be made. I wanna see it and the world wants to see it,” said Wallin.
