West Ham United have been knocked out of the FA Cup after being on the end of a 5-0 thrashing at home to Manchester City last Friday evening.

City’s goals came courtesy of Yaya Toure, a Havard Nordtveit own goal, David Silva, Sergio Aguero and John Stones.

The Sky Blues will face an away trip to either Bolton Wanderers or Crystal Palace at the next stage of the competition.

Slaven Bilic’s side can now put all their focus onto their Premier League campaign. They face a London derby at home to Crystal Palace on Saturday afternoon. The Hammers are currently 13th in the league table and a win at the weekend could see them return to the top-half of the table.

Bilic’s team have struggled severely at the back this season. They have only kept two clean sheets in all competitions since November. They have also struggled with injuries at lot this season, meaning that they have spent a lot of this season depleted.

If West Ham want to save their season, they will need to add some more defenders to their squad in the current transfer window.

Shoot! looks at two defenders that West Ham should sign in this month’s transfer window…

Kieran Trippier

The Tottenham Hotspur right-back would be a very good signing for West Ham.

Since arriving at White Hart Lane, Trippier has struggled to gain much first-team action.

The 26-year-old has only played nine times for Spurs in all competitions this campaign.

He seriously impressed whilst at Burnley and a right-back of his calibre does not deserve to sit on the bench

Hammers defender Sam Byram has struggled with injuries this season, so Trippier would be a great addition to the squad.

The 32-year-old Serbian’s Chelsea contract expires at the end of this season.

Ivanovic has won everything possible at Chelsea and he even scored the winner in their 2013 Europa League success.

The Serbian has been very much out of favour at Stamford Bridge this season. He is versatile and is accomplished at both right-back and centre-back.

As the Hammers are struggling for defensive experience, Ivanovic would be both a great player and mentor as he’s coming towards the end of his career.

The veteran still has a good couple of seasons left at the high end of the Premier League and he would be very cheap given his short contract.
