Former Manchester United midfielder Ray Wilkins feels his old club needs to buy proven experience.
United lost Rio Ferdinand, Nemanja Vidic and Patrice Evra this summer and have so far only signed Luke Shaw - the 19-year-old - from Southampton as replacement in defence, as well midfielder Ander Herrera.
"It's all doom and gloom at Old Trafford, but I don't see why it should be," he said on talkSPORT.
"I'm sure before the transfer window closes they will add a couple of names to that. They already have a good squad and they need to add some top class names.
"It's basically the same squad of players. What has happened with Ander Herrera and Luke Shaw going to the club is that they've bought potential. If you look at Jose Mourinho, he buys the proven article and this is what Manchester United need.
