West Ham boss Manuel Pellegrini is looking to sign one more striker to his ranks in the summer transfer window despite signing Sebastian Haller on a club-record transfer fee.
The Hammers lost Marko Arnautovic, Andy Carroll and Lucas Perez this summer, while the future of Javier Hernandez is up in the air.
In recent weeks, West Ham have been linked with a move for Glasgow Rangers striker Alfredo Morelos. The Colombian striker scored 32 goals last season but his poor disciplinary records go against him.
With that in mind, the Hammers must make a move for Juventus striker Mario Mandzukic who could leave the Bianconeri this summer following the arrival of Maurizio Sarri.
