Bilic took over from Sam Allardyce at Upton Park last summer, and he has made a big initial impression with the London club.
The Croatian boss has guided West Ham to the brink of the top four and he has done so in style.
West Ham have been one of the most entertaining sides in England to watch this season, with their attacking style winning over the Upton Park faithful.
And Collymore said: “Many people thought he’d struggle at Upton Park, that he wasn’t ready for the Premier League but, having locked horns with him during our playing days, I always felt he had what it takes to succeed here.
“I always thought you could tell a lot about a man from the handshake you received at the end of a game, about his character, the man himself and not just the footballer. Bilic would always be chatty, friendly and polite.”
Bilic’s friendly persona is combined with a fierce desire to win, and he has certainly taken the club forward.
West Ham have brought in some wonderful talent and the future looks bright, with a move to the Olympic Stadium on the horizon.
The Hammers will hope that they can bring European football to their new ground next season, and they are currently hot on the heels of Manchester City and Arsenal in the race for a Champions League qualification spot.
