West Ham are reluctant to sanction a sale for Lucas Paqueta this month amid interest in the player from Brazil, reports BBC Sport's senior football correspondent Sami Mokbel.
Sources have indicated that at least two clubs in Paqueta's homeland, one of which is Flamengo, have shown an interest in the Brazil international in this transfer window.
Paqueta has 18 months remaining on his contract and is expected to leave West Ham either this month or in the summer.
It is understood Flamengo would be willing to table an offer of about £35m.
What do you think the Hammers should do? Should they cash in now for a good price, or is he too important to lose in the battle for Premier League survival?
