West Ham’s planned transfer activity this summer could see them raid relegated outfits from the Premier League, as they seek to improve their defence.

The Hammers are in need of additional recruits this summer and bolstering the defence is a priority for Slaven Bilic’s side, who’ve shipped 59 goals this season- the third-highest tally in the Premier League.

Only Swansea City and Hull City have conceded more goals than West Ham this season and the Hammers will fight a Premier League rival for a signature of an established defender this summer.

Football.London¬†reports that West Ham will fight Crystal Palace for the signature of Sunderland centre-half Lamine Kone,¬†who’s likely to leave the North East if the Black Cats are relegated.

Sunderland currently sit rock-bottom of the Premier League, 12 points from safety with six games remaining and their relegation could be confirmed in the next few weeks.

West Ham have turned their attention to Kone after Liverpool raised their asking price for Mamadou Sakho, who’s defensive performances have helped turn Crystal Palace’s season around.

The loanee is likely to leave Anfield on a permanent deal this summer but Jurgen Klopp’s asking price may leave the Hammers having to look elsewhere.
