He told WHUFC.com “We are very pleased to complete the signings of Issa and Lukasz and, on behalf of everyone at West Ham United, I would like to welcome them both to London Stadium, Issa is a defender with great talent and character. He is only 21 but he has already established himself as a key player over a period of time with Toulouse.”
“We believe he has defensive qualities that will be well suited to the Premier League – pace, power and a sharp concentration – and I also feel he will complement the other central defenders we have.
Pellegrini added: “With Lukasz, we have secured a proven Premier League goalkeeper who has great experience at this level. We believe he has a number of good years ahead of him – hopefully his best – and there is no doubt that he will give us excellent competition for the number one spot.
“It is important, as a Premier League club, to have strong goalkeepers who can push each other and we have that dynamic with Lukasz and Adrian now. I look forward to working with both Issa and Lukasz when they report for pre-season training next month. I wish them the very best in their careers with West Ham United.”
