Sky Sports pundit Jamie Carragher thinks West Ham would be making a mistake if they decide to part ways with Slaven Bilic.

The Croatian manager arrived in East London last summer and enjoyed a hugely successful maiden campaign at the Hammers, eventually finishing seventh after a negotiating a top four battle for most of the season.

But this season is yet to witness the same form that has the Hammers down as one of the teams other top-flight sides were worried about playing.

West Ham have lost five of their opening six Premier League games this term and have also been eliminated from the Europa League at the final qualifying stage. Injuries to key players and the move to a new stadium haven't helped, but there are already question marks over Bilic's future.

However, Jamie Carragher insists West Ham should not make any rash decisions and hope the West Ham board they there have been a number of unlucky factors that have contributed to Bilic's poor start this season.

Carragher wrote in his Daily Mail column: "Talks haven't taken place over a new contract for Bilic but I hope the board don't do anything silly.

"He is a good manager and circumstances have contributed to this start, such as Winston Reid - a player I hold in high regard - struggling for form and Cresswell's long term injury."

And in a poll we ran earlier this week, we revealed that 80% of West Ham fans still have faith in Bilic's abilities to turn the current form around.

But despite Carragher's positive words for Bilic, the same cannot be said for the business West Ham conducted in the summer.

The Liverpool legend wrote that he hasn't been impressed with the Hammers' summer business and questioned who was behind the decision making.

"What West Ham needed to consolidate was a really good striker," he wrote.

"They tried plenty of options but it looked to me like they panicked when spending £20million on Andre Ayew from Swansea — I couldn’t believe that fee — and taking Simone Zaza on a season-long loan.

"Aside from that, they added squad players in Havard Nordtveit, Sofiane Feghouli and Jonathan Calleri, who they don’t need now they are out of Europe.

"Meanwhile, Arthur Masuaku, the left back brought in to replace the injured Aaron Cresswell, has had an awful start. I’m never quite sure who is making the decisions in terms of transfers at West Ham. Is it Bilic? Is it the owners?

"Really, the whole policy feels scattergun. They spent an awful lot of money without improving what they already had."
