It's about that time of year where kit leaks are big news and like most other clubs West Ham United will be bringing out a new strip this summer.

The Hammers will be going into their third season of a five-year £20million deal with kit makers Umbro.

Umbro produced the first-ever West Ham replica kits for sale in the 1960s when the likes of World Cup winners Bobby Moore, Sir Geoff Hurst and Martin Peters famously wore the claret and blue in their 1964 FA Cup and 1965 European Cup Winners' Cup triumphs.

And the sportswear giant has proved something of a lucky charm for the club as they were reunited for last season's superb and record-breaking farewell season at the Boleyn Ground when Slaven Bilic's side finished just four points off the Champions League places.

After producing a well received kit for that last ever season at Upton Park, Umbro stuck to a similar format for the first season at their new Olympic Stadium home.

It is anticipated Umbro and the Hammers may well take inspiration from the hugely popular kits of the 1980s in their next strip.

Indeed Hammers co-owner David Gold even appeared to endorse one of the most popular concept kits doing the rounds - which takes inspiration from the strips between 1983 and 1985 - by retweeting the post showing off the design.
