With their Premier League survival still somewhat in doubt, planning for the summer is unlikely to be David Moyes' priority right now.

The Hammers currently sit 16th in the Premier League table, but are only clear of the bottom three on goal difference.

A porous defence has perhaps been their biggest weakness so far this term.

Only Norwich City, Aston Villa and Southampton have conceded more than the Hammers in the league this term, who have let in 50 goals from their 29 fixtures.

Their offensive play has been slightly better, but their remain doubts about the form of Sebastien Haller.

Signed for big money last summer from Eintracht Frankfurt the striker has scored seven goals from 27 league appearances, but has managed just three goals since October.

In midfield, the signing of Pablo Fornals has not yet borne fruit, with the Spaniard making just 15 starts, while injuries have continued to plague Jack Wilshere.

Here, we look at five players the club should target this summer...

Hirving Lozano

A player that has been linked with the Hammers in recent weeks, Lozano is an exciting talent that can play across the front line.

The 24-year-old was highly rated prior to his move to Europe, but has managed just two Serie A goals for Napoli in 16 appearances so far this season.

However, prior to his move to Italy he was prolific for PSV Eindhoven in the Eredivisie and would hope to rediscover that form at West Ham.

With Felipe Anderson scoring once this term for the Hammers and injuries restricting Yarmolenko to just nine starts, Lozano could add quality in area Moyes needs it.

Serhou Guirassy

Reportedly available for around £15m, Amiens forward Serhou Guirassy is name that has been linked with the club recently.

With nine goals in 23 Ligue 1 appearances this term he has not been prolific, but with Amiens relegated after picking up just 23 points from 28 matches, he was a bright spot.

An able hold up man who excels in the air, Guirassy really found his best form towards the end of the season and scored five times in his last seven matches of the year.

If he was to come to East London he would likely play back up to Haller, but with the ability to also play out wide, he offers a good value option.

William Carvalho

Portugal's William Carvalho

A name that has been linked with a move to the Premier League for many years is William Carvalho, but with the Portugal international apparently keen on a move to England, the deal could finally happen.

Despite his injuries concerns Carvalho is a player of plenty of talent and in the current environment could be available for less than the £20m Real Betis paid for him in the summer of 2018.

The 28-year-old has been restricted to just nine league appearances this term and with Wilshere's injuries proving a real difficulty for the club, they may want to avoid signing another injury prone midfielder.

However, if they can secure him for a cut price and get him fit, he is an international with plenty of quality that could make a difference.

Tim Krul

With Lukasz Fabianski now 35 years old, finding a solution in the goalkeeper position must be a priority for the summer.

The addition of Roberto Jimenez did not work last year, with the Spaniard making a number of high-profile errors.

If money is short this summer one player that could represent a good option is Tim Krul, who has made the fourth-highest number of saves this term.

The Dutchman's form this season saw him earn an international recall and with Norwich City likely to be relegated, he could be available at a cut-price.

Gonzalo Montiel

One player West Ham already look to be closing in on is Argentine defender Gonzalo Montiel.

According to reports in Spain, the River Plate man already agreed to join the Hammers, with a work permit the only potential stumbling block.

At 23 years old, he will bring some much-needed youth to the back line and having just made his national team debut, he is highly-rated back home.

With Pablo Zabaleta now 35 and a potential departure this summer and Ryan Fredericks managing just 19 starts this season, Montiel looks to be a smart deal.
