At Upton Park, West Ham prepared for that derby showdown with a 3-2 success against Italian team Sampdoria.

Youngster Reece Burke got the winner in the last minute to ease the pressure on Sam Allardyce as West Ham finally earned their first pre-season victory.

Since the end of last season, Saints fans have seen Adam Lallana, Luke Shaw, Rickie Lambert, Calum Chambers and Dejan Lovren all sold, with new boss Ronald Koeman struggling to find quality replacements.

Leicester, promoted as Championship winners, enjoyed a 1-0 win over German outfit Werder Bremen thanks to defender Wes Morgan's seventh minute header.
