Wayne Rooney has called out Aaron Wan-Bissaka for not providing enough attacking threat which could see him axed at Manchester United.
The young right-back has impressed massively since he moved from Crystal Palace just over 12 months ago.
Rio Ferdinand hailed the 22-year-old as the best one-on-one defender in the world last season.
But his lack of influence in the final third, where full-backs have become increasingly influential, has seen Rooney call on his former club to dip into the transfer market.
Brighton's Tariq Lamptey, who is another player to emerge from Chelsea's academy, has been identified as a potential target.
Although the now Derby man has called out United's recruitment that has been widely criticised this summer.
He told the Times: “That Fernandes and Van de Beek — United’s last major signings — are two very good players who prefer the same position is another example of how their buying could have been more targeted.
“Personally, if I were doing their recruiting, as well as that No 9 I’d go for another centre half to partner Harry Maguire and try for Brighton & Hove Albion’s Tariq Lamptey, who looks a brilliant attacking right back.
“While Aaron Wan-Bissaka has done OK defensively, you want United full backs to put the opposition on the back foot when the team have the ball and I don’t think he does that.
How many players do Man Utd need to sign before the window closes? Have your say here.
“Luke Shaw can at times but you always worry from a fitness point of view whether he can do it for 90 minutes so I think full back is an area where United could really improve.
“The game has changed and where before your full backs didn’t have to be attacking players, they just had to provide overlaps and be an option.
"Nowadays they have to play a full part going forward — flooding the gaps when wide strikers such as Rashford come in from the sides.”
