Former Manchester United defender Paul Parker has said that Victor Lindelof and Harry Maguire are not good enough to line up for the club.
The pair, who are believed to have cost a combined £120m, played together on Wednesday as the Red Devils lost 2-0 to Arsenal at the Emirates Stadium.
Speaking to Goal.com, Parker bemoaned their performances and said: "Harry Maguire and Victor Lindelof are not good enough. I don't know how they are going to improve on the two of them.
"They still have players who won't be taking United forward when you consider defenders like Jaap Stam, Rio Ferdinand and Nemanja Vidic who were vital when United teams were winning.
"A lot of people are talking about how much money United need to spend to bring in new defenders but what they are not thinking about is whether the players will actually want to come to Old Trafford right now."
