According to O Jogo (translated by Sportwitness), the Hammers are keen on the player but they are yet to open talks for him.
David Moyes is looking to bring in an attacker this month and the 27-year-old is an option. The 64-cap Switzerland international has been linked with Tottenham as well.
Seferovic has scored six goals and he has four assists to his name this season. He could prove to be a decent partner for Haller in the attack.
The former Bundesliga star needs someone to share the goalscoring burden. Also, Seferovic’s arrival would give Moyes some much-needed depth in attack.
