Chelsea legend Ruud Gullit has taken fresh aim at Manchester United boss Louis van Gaal. Gullit is perplexed by the signings of Van Gaal at Manchester United, with the likes of Angel Di Maria, Radamel Falcao, Ander Herrera, Luke Shaw, Daley Blind and Marcos Rojo coming in for £170million even though United have neglected to sign central defenders.

He said in his column for De Telegraaf: "How on earth is it possible that such an experienced and successful manager thought he could start the season at Man United without buying a couple of really strong central defenders?

"I am still amazed by his buying and his transfers. If you only strengthen the midfield and the attack, than you are underestimating the level and the power of the Premier League. If you want to survive in the top flight of English football you start with the foundation and you build the roof of your house last. Van Gaal has done it the other way round.

"After the departure of Nemanja Vidic to Inter, and Rio Ferdinand to QPR it was obvious that new central defenders were needed. And he had 200 million in his chequebook to spend. If you don't use part of that to buy strong, experienced central defenders you have the wrong idea about the Premier League.

"Now matters are even worse because of all the injuries in his defence. He is having to fill one gap after another. And if you have so many injuries and you have not bought the defenders, than you are doing something wrong at your club."
