The new training headquarters have been dramatically upgraded over the summer and the players are able to train on four brand new pitches and enjoy top class facilities throughout the complex.
Speaking to the official site, Slav said: “Rush Green is exactly what me and my staff wanted. We were delighted to start at home with a great victory in Europe on Thursday and now we have training facilities that go hand in hand with the Stadium.
“The Club has done what we wanted so I have to thank the Chairmen and the Board.
“We wanted to make a very good, cosy training ground that the players would enjoy to go to a couple of hours before training and stay there two or three hours afterwards. Somewhere they can bring their kids sometimes.
“I’m really happy with the job they have done.”
West Ham United’s Head of Medical and Sports Science Stijn Vandebroucke said: “The whole training ground has been designed for the players and designed to be compact so that we keep the spirit which is so important at West Ham United. This is our identity.
“The dressing room is much bigger and we have great recovery for the players where they have a sauna and plunge pool.
“We have a big gym and a fantastic treatment room where all the players needs are catered for.
“We have also heavily invested in the quality of our pitches where we already have four to choose from and several more in the coming months.”
Head Groundsman Dougie Robertson added: “The changes are huge. The facilities that are now available really brings us into the big league and that is where the Club wants to be. The Club has done a fantastic job getting the players what they require and hopefully they can do the same in the league.
“We are incredibly fortunate that we will have different kind of pitches for the players to train on.
