Former Juventus defender Angelo Ogbonna has said he believes "not much will change" for the club without Paul Pogba.
Juventus told ESPN FC on Sunday that Pogba had been given permission to have a medical at Manchester United, with the Premier League club confirming the news two hours later.
When the deal is completed, it is set to break the world record transfer fee and expected to be around £95 million plus £20m in agent fees.
Ogbonna, who now plays for West Ham, was a teammate of France international Pogba at Juventus for two seasons from summer 2013.
The 28-year-old, who played as the Hammers lost 3-2 to Juve in a friendly on Sunday, told Gazzetta World: "I think they can [compete for the Champions League without Pogba].
"They have a really good team and squad. They'll miss Pogba, but they've got [Miralem] Pjanic and [Gonzalo] Higuain, so they've got a lot of quality and not much will change."
United manager Jose Mourinho said it was "amazing" that Pogba was set to return to the club after leaving in 2012, but added that the midfielder would have to work hard to get into the team.
When asked about the Pogba move after his side's Community Shield win over Leicester City at Wembley, Mourinho told BT Sport: "It's an amazing situation that such a great player is with us. Finally we have him.
"He comes to a winning side, who have won the FA Cup Final and the Community Shield. He has to work hard to come to the team."
