It was Salthouse who signed Ryan Fredericks earlier this summer and recently helped broker the deal for Andriy Yarmolenko who is expected to be officially announced later today by the club.
Salthouse is also the agent for Aaron Cresswell who has also linked been previously with a possible move away from the club.
Salthouse also helped broker the deal to bring Marko Arnautovic and Sead Hasanović in a connected deal but also has his fingers in a lot of deals as he often acts as an intermediary who seems to be favored by West Ham at this moment.
