West Ham boss Manuel Pellegrini is still on the lookout for further summer signings before the transfer window closes shut next month.
Pellegrini has already bolstered his squad significantly with the additions of Felipe Anderson, Andriy Yarmolenko and Jack Wilshere to name a few.
But the Chilean seems intent on bringing in at least two more new names through the door with one of them possibly being a central defender.
The Swans value Mawson at over £20m and have previously turned down offers from the Hammers for the 24-year-old.
Since then, West Ham have gone on to sign Issa Diop and Fabian Balbuena with Pellegrini identifying central defence as an area of the squad that needed strengthening.
As well as Diop and Balbuena, Pellegrini also has Angelo Ogbonna and Winston Reid to call upon — although the latter is currently injured — when selecting his central defensive partnership.
With all of that in mind, forking out £20m-plus on £13.5m-rated (via Transfermarkt) Mawson may not be the wisest of moves for West Ham.
There is no denying the centre-back’s ability. He was one of Swansea’s better performers in the club’s dismal Premier League campaign last season.
The former Barnsley defender put in a tonne of commanding performances, was aerially dominant and always looked comfortable in possession and when playing out from the back.
But given that West Ham already have Diop, Balbuena, Ogbonna and Reid all on their books, it is hard to see Pellegrini splashing the cash on another central defender.
Assessing the Hammers’ squad, midfield may be the department that is in most need of reinforcements, rather than central defence, with both Pedro Obiang and Cheikhou Kouyate’s futures at the London Stadium uncertain.
