Manchester United have received encouragement in their Paul Pogba chase after Real Madrid manager Zinedine Zidane admitted that it will be difficult for him to improve his squad by making a big signing. The Juventus midfielder has been linked with the Red Devils, while the Champions League winners are also believed to be in the mix for his signature.

According to Sky Sports, the 20-time English champions are ready to pay a world-record fee of £100m ($132.3m) in bringing the France international back to Old Trafford. He left United as a free agent in 2012 and since then has won four Serie A titles with the Turin club.

The Spanish capital club are also interested in securing the services of Pogba in the summer transfer window, reports Spanish newspaper AS. Real had urged the midfielder's agent, Mino Raiola, to provide more time to formulate a deal for the 23-year-old star.

However, Zidane has hinted that his side will not be looking at any marquee signings after revealing his admiration for his compatriot.

"I like Pogba. At the moment, he's a Juventus player. I'm happy with the squad I have and it's difficult to improve it," Goal.com quoted Zidane as saying.

"But after saying that, I like Pogba. Yes! He is a good player. He is not the only one, because there are many good players, and every club want to have good players. But he is playing for Juventus

"It's difficult because a big squad creates problems. But I don't dislike the idea of looking to the academy. There are a lot of competitions and we need everyone.

"Working is the most important thing; it's what we're going to do here. Then, bit by bit, we'll decide things. You don't know what will happen until August 31. We're happy with the squad we have and we've just won the Champions League."

Zidane's latest comments could be seen as boosting United's ongoing pursuit of Pogba. Jose Mourinho has seen his new club complete three signings and the Manchester Evening News reports the former Chelsea boss wants to make the Juventus star as his fourth summer signing.
