West Ham are interested in signing AC Milan forward M'Baye Niang, according to Sky in Italy.
Milan value the 22-year-old at £13m, but would consider a loan with an option to buy in the summer.
Sky in Italy understand Crystal Palace, Everton and Genoa are also interested in signing Niang, who has scored three goals in 18 Serie A appearances this season.
Niang netted five times in 14 matches during a brief spell on loan at Genoa in 2015 and Sky sources understand that a move back to Genoa is his most likely destination.
Meanwhile, West Ham are in talks with La Liga side Las Palmas over a deal for Jonathan Calleri.
The Argentine forward has endured a difficult spell with the Hammers since joining on a season-long loan from Deportivo Maldonado in August, but did score his first goal for the club in last Saturday's 3-1 win at Middlesbrough.
Las Palmas president Miguel Angel Ramirez claims West Ham have delayed making a decision on the proposed deal as they weigh-up whether to cancel Calleri's loan spell with the club.
"[Jonathan] Calleri and Hernan Toledo are two players that interest [us]," Ramirez told Spanish newspaper Marca.
"We were expecting an answer from West Ham in order to make the Calleri thing (deal) official, but they have asked us for a few days."
