Since turning professional in 2015, the Scotsman has competed solely in the super-lightweight division, where he is the reigning undisputed world champion.
Nicknamed ‘The Tartan Tornado’ for his aggressive style, Taylor, 31, is one of boxing‘s current pound-for-pound stars and has established himself as one of the most deadliest men on the planet.
Next up the Scottish poster boy will defend his WBA (Super), WBC, IBF and WBO belts against Jack Catterall on February 26 at the OVO Hydro in Glasgow. It will be the first time he has fought in front of a home crowd since May 2019.
But Arum – who has promoted Taylor in his last three fights – reckons his future lies at welterweight.
However, he warned his charge not to look past the dangerous Catterall, who is currently riding a 26-fight undefeated streak.
Arum told Sky Sports: “There are a lot of hungry people on our side of the water, like Teofimo Lopez and Jose Zepeda, who want to challenge him.
“Or Josh could move up in weight to fight Crawford or Errol Spence Jr or any of the 147lbs fighters.
“He isn’t lacking in opponents.
“But let’s get the Catterall fight over with.
“When these fighters look ahead and don’t concentrate on the fight in front of them, that’s when they get beaten.
“Josh is a great talent and the sky is the limit for him.”
Crawford, meanwhile, has opened the door to facing Taylor in a fight which would pit two undisputed champions against each other.
Speaking recently to Sky Sports, he said: “Of course, in the future.
“I’m not opposed to any of it. If that fight makes sense and that fight is the fight that’s in front of me, then of course.
“If it makes sense, it makes sense.
“I’m a businessman at the end of the day and that would be a great fight as well.”
