Redding raced in MotoGP from 2014 to '18, riding for Honda, Ducati and Aprilia in that time, before switching to British Superbikes last year and winning the title as a rookie.
He subsequently switched to WSBK as a factory Ducati rider and scored a trio of third places on his first race weekend in the series at Phillip Island earlier in the year.

"For me he could still try," said Guidotti of Razgatlioglu. "He's still at an age he could do it. If he waits too long though, he risks losing the right moment.
"I think he's still got a couple of years to try and make the move here before he gets too much into Superbike. When a rider arrives who is still mentally predisposed to change and physically intact, with an important confidence in his own means, he can do it.
"If he is still in Superbike too much and he doesn't win, the confidence will be lost, so he won't be in MotoGP in the ideal mental condition to make the jump from Superbike to MotoGP."
