Manchester United hero Denis Irwin insists Fred will soon prove his value.

Irwin is confident manager Jose Mourinho's approach will benefit the midfielder.

"The manager, like he did with [Victor] Lindelof, he is letting Fred settle and get used to the pace of the Premier League," Irwin said on MUTV.

"He came across from Shakhtar and I can't imagine the pace across there is anywhere near our league.

“I think you'll see the best of Fred in the coming few months. He is aggressive, runs around and is energetic.

“I think we'll see more of Fred, I really do."
