West Ham co-owner David Sullivan told David Moyes “I’ve got you a present” after sealing deal for Slavia Prague midfielder Tomas Soucek, Football Insider understands.

The Premier League club are set to make Soucek their second signing of the January window following the earlier capture of goalkeeper Darren Randolph.

A West Ham source has told Football Insider that Soucek is finalising a £17million move today as he undergoes a medical and puts pen to paper on a contract.

It is a deal that has come out of the blue as Sullivan, who has taken charge of transfer negotiations this month, works to bolster Moyes’ struggling team.

Renowned for favouring a coterie of agents, brokers and middle men, the long-standing chairman has negotiated the Soucek deal and was delighted to have informed Moyes it is all but complete.

Soucek is not expected to be the last arrival at the London Stadium this month, with the real prospect of a late-signing blizzard following months of wretched results.

The Hammers are also continuing to explore options to reinforce their attack and at full-back before the window shuts on Friday night.

Randolph became the club’s first January signing when a protracted deal was completed for him to join from Middlesbrough for over £3m.

Soucek is also in line to join after making huge impact for Slavia Prague this season, including in the Champions League.

The goalscoring midfielder has scored eight times in 17 league games and also found the net twice in the Champions League.
