West Ham's primary focus in this transfer window so far has been in defence and midfield.

The east London club have added the likes of Lukasz Fabianski, Issa Diop and Ryan Fredericks to their ranks while Jack Wilshere, Jean-Michael Seri and Felipe Anderson are said to be targets for midfield and attacking midfield respectively.

West Ham, though, could also probably do with bringing in a new striker. Javier Hernandez's future remains uncertain and Andy Carroll is injured more often than not, potentially leaving Marko Arnautovic as the Hammers' only real threat up front for the upcoming season.

With that in mind, West Ham should resurrect their interest in Celtic's Moussa Dembele to improve their forward options.

The Daily Express reported last summer that the Hammers had targeted Dembele for a move to the London Stadium and, while nothing materialised back then, now would be the perfect time to finally get a deal done for the 21-year-old.

Dembele, who is valued at £5.4m by Transfermarkt, has enjoyed a good spell in Scotland with his debut season at Celtic standing out in particular. The Frenchman scored 32 goals in all competitions including the Champions League where he impressed in the SPL champions 3-3 draw against Pep Guardiola's Manchester City.

The former Fulham striker possesses the sort of goalscoring ability that can help elevate West Ham and, ultimately, give manager Manuel Pellegrini another reliable alternative to Arnautovic up front.

Much could depend on what happens with Hernandez but, with Carroll's injury record and no guarantee that Arnautovic will carry on as a striker, an offer for Dembele should be readied.
