Alex Song is set to return to Upton Park despite serious injury concerns and a disappointing end to last season's loan spell at Upton Park
West Ham co-owner David Sullivan has admitted resigning Alex Song on a permanent basis represents a gamble on the part of the London club.
The Cameroonian midfielder spent last season on loan at Upton Park from Barcelona, making 31 appearances in all competitions.
The former Arsenal man's form tailed off towards the end of the season, however, and Sullivan has pinpointed concerns attached to the deal.
Speaking to the Knees Up Mother Brown podcast, Sullivan confirmed a deal is in place pending a medical, and talked about Song's range in form last season.
