West Ham have been one of the busiest teams in the transfer window this summer and, to the delight of supporters, some of the acquisitions made have been quality ones. 

The likes of Andriy Yarmolenko and Felipe Anderson are of the calibre fans had been expecting since the club's move from Upton Park to the London Stadium.

As well as Yarmolenko and Anderson, Manuel Pellegrini has also added centre-back Fabian Balbuena to his squad to strengthen his central defensive options, on top of Issa Diop, who was signed earlier in the window.

With his central defence reinforced, Pellegrini may now look at bringing in a new left-back, and signing Paris Saint-Germain's Layvin Kurzawa would be another bold move.

After buying both Neymar for £200m and Kylian Mbappe for £165m (via BBC Sport), PSG are desperate to sell this summer in order to comply with UEFA Financial Fair Play regulations, and £18m-rated (via Transfermarkt) Kurzawa is one name rumoured to be on the Ligue 1 champions' transfer list.

There are some questions marks surrounding Kurzawa's ability defensively, though, a coach like Pellegrini could easily fine-tune the 25-year-old into a complete full-back.

Kurzawa is already one of the best attacking left-backs in European football and, despite not yet striking total balance in his game, the France international would be an upgrade on both Aaron Cresswell and Arthur Masuaku.
