West Ham United are set to rock Everton with a mega offer for star striker Andy Johnson.

The Daily Mail says West Ham will enter the summer spending frenzy with a £13million offer for Johnson and the promise of £90,000-a-week wages.

The deal, which would more than double Johnson's earnings at Everton, would be worth £4.7m a year.

The England striker is aware of the interest and although West Ham expect Everton to rebuff their opening bid, the London club are prepared to go as high as £18m, which could prove too good to turn down.
