James Collins has admitted that West Ham United’s players ‘haven’t been happy’ with their performances so far this season.

Speaking after the crucial victory over Watford at the weekend, the centre-back expressed his delight at the result but stressed that there is still room for improvement in all areas.

“There’s more to come from this team,” the former Wales international told the club’s official website.

“We haven’t been happy with the season at all.

“Saturday was good, but we can certainly improve all over the pitch in terms of consistency.”

A 3-1 defeat at Brighton & Hove Albion in the previous Premier League fixture meant that the clash with the Hornets became something of a ‘must-win’ for Collins and his team-mates.

As well as the positive scoreline, fans will no doubt have been pleased with a display which the 34-year-old described as ‘chalk and cheese’ compared to their showing at the Amex Stadium.

Meanwhile, Collins talked up the contribution of Marko Arnautovic, who bagged the second goal to put the game beyond Saturday’s opponents.

Lauding the Austrian as ‘a massive player’ for the club, the ex-Aston Villa star added that if the forward can steer clear of injuries then the Hammers would have a greater chance to climb up the standings.

Arnautovic had a difficult start to life in East London but has turned his early season form around following David Moyes’ arrival as manager in November.

The 28-year-old has seven goals and three assists in his last nine appearances in the top flight and is one of the in-form players in the division.

West Ham’s exit from the FA Cup at the hands of Wigan Athletic in January means they have no match to play this weekend, with an away trip to Liverpool the only remaining fixture this month.
