According to Bleacher Report, West Ham United co-owner David Sullivan has previously told Brazilian midfielder Felipe Anderson he will be allowed to leave should be a Premier League top-six club come for him with a bid in the region of £75million.
The winger arrived London Stadium from Lazio for £35million last summer, and has already been linked with Real Madrid following an impressive form that has already earned him a recall to the national team.
It is believed that West Ham have now grown increasingly worried that clubs will come after the signature of the ambitious Anderson this summer, and will most likely offer him an improved contract at the end of the season.
