West Ham are reportedly closing in on the signing of Toulouse defender Issa Diop.

Diop was apparently set to fly to London yesterday to agree personal terms and undergo a medical, after the two clubs agreed a fee of £21.9m for the centre-back.

The 21-year-old has been linked with a move to the London Stadium for the past week and it seems like the Hammers have now got their man, fending off interest from Sevilla, Marseille, Monaco and RB Leipzig for his signature.

Improving the defence has clearly been a priority for new boss Manuel Pellegrini after the Hammers completed a move for Fulham right-back Ryan Fredericks two weeks ago, who penned a four-year deal at the London Stadium.

Diop will become West Ham’s second summer signing if all goes smoothly and the 21-year-old will arrive at the London Stadium with some pedigree, having been capped at u21 level by France.

The centre-back impressed in France last season, scoring three goals in 37 appearances in all competitions, helping Toulouse retain their Ligue 1 status for another season.

In other transfer news, Diop could also be joined at the London Stadium by Lukasz Fabianski, with the Hammers reportedly locked in talks with Swansea over a £7m move for the Polish goalkeeper.
