Terzic said: “He was one of the best players in the league last year so he is raising our quality and our level and taking us to the next step. He is very experienced and very funny. He is always in a good mood and his dressing style is a little bit crazy but he is very important for the team.”
Terzic was speaking at the end of a behind-closed-doors friendly between the Hammers and Crystal Palace, in which Song played 60 minutes of action.
It was his first taste of match action of the season, having spent the first months of the campaign recovering from an injury suffered over the summer. His return is long-awaited, but he has become something of a forgotten signing due to the success of the other summer arrivals.
Song already had the ankle injury when Slaven Bilic agreed the deal to bring him back to the Boleyn Ground on a season long loan, believing that the midfielder could replicate the form he showed in East London last term.
At times he was one of the best midfielders in the Premier League, and if he can get anywhere near the same level of form, West Ham will further strengthen an already strong side.
Terzic has high praise for Song, and was delighted to see the midfielder play for as long as he did in the friendly against Palace, which the Hammers won 1-0.
He looks to be close to full match fitness, and it would come as no surprise to see Song taking to the field in a competitive game before too long.
