West Ham United announced on Tuesday that they had completed the signing of French defender Issa Diop from Toulouse for a club-record fee.

The 21-year-old has signed a five-year contract at the London Stadium, and is a coup for the capital outfit when considering the interest surrounding him.

It is expected to be a busy summer for West Ham, and new head coach Manuel Pellegrini has further boosted his defence following the signing of Ryan Fredericks from Fulham.

Diop, who is valued at £19.8m by transfermarkt.co.uk, leaves Toulouse having made 95 first-team appearances for the French club, which is very impressive for a man of his age.

Last term, meanwhile, the centre-back scored three times in 34 Ligue 1 appearances.

It is certainly a statement of intent from the West Ham owners, and the club's supporters have been on social media reacting to the deal.

It would be fair to say that the fans are absolutely delighted that Diop will be turning out in a West Ham shirt at the London Stadium next season.
