The father of Zenit St Petersburg midfielder Axel Witsel admits a move to Juventus is an "option".

The Belgian could be on the move this summer.

"Axel has never regretted his transfer from Benfica to Zenit, but three years in St Petersburg are enough," Thierry Witsel told hln.be.

"We hope to leave in style with a title in our pockets. For the moment Zenit have an eight-point advantage over second place.

"Juventus? They are an option, but not the only ones. We haven't made any decisions yet."
