Transfer Deadline Day: Every Premier League Club's Best Signing Of The Window

2. West Ham - Sebastien Haller

West Ham may not have set the world on fire this transfer window but have certainly improved their squad with some impressive signings. They've brought in Roberto from Espanyol as a backup for Fabianski alongside Villareal playmaker Pablo Fornals, but the star signing of West Ham's window has to be Sebastien Haller.

The Frenchman was impressive for Frankfurt last season, scoring 15 and assisting 9 goals in 29 games. His physical presence will likely combine well with the pace that players like Michail Antonio and Felipe Anderson bring. With Marko Arnautovic leaving the club for Shanghai SIPG, The Hammers are in desperate need of attacking quality and the signing of Haller is a fantastic means of obtaining that.

West Ham may may have also completed the signing of Albian Ajeti from FC Basel this deadline day, but he will likely be unable to top the quality that Haller brings to the side.
