West Ham United are reportedly scouting Europe for a new striker after Andy Carroll was ruled out until October with a knee injury.

The Hammers have already had bids for Manchester United's Javier Hernandez and Chelsea's Loic Remy rejected, while they are unwilling to match QPR's £15million valuation of Charlie Austin.

West Ham have also been linked with Roma's Mattia Destro and Tottenham's Emmanuel Adebayor, but it is understood neither player is a realistic chance of making the move to Upton Park.

With a number of options exhausted, The Mirror is reporting West Ham have stepped-up their efforts to find reinforcements for their frontline as concerns over Carroll's health continue to arise.

The east London club currently have Diafra Sakho, Enner Valencia and Mauro Zarate as the other strikers on their books.
