West Ham supporters have had a lot to be happy about since Slaven Bilic's arrival at the club.  The Hammers have enjoyed their best Premier League season in recent history and could even mount a late charge for the final Champions League qualification place.

​That combined with the prospect of an FA Cup semi-final against Everton - if they can overcome Man Utd on Wednesday - has seen a new-found belief among West Ham fans that believe Slaven Bilic is the man to take them to the next level.

Last summer West Ham spent money wisely, they recruited Dimitri Payet from Marseille for £10.7m and Michail Antonio from Nottingham Forest for £7m, while also adding defensive reinforcements with the likes of Angelo Ogbonna and Pedro Obiang from Serie A.

However, Bilic has confirmed that he would like to add a few names ahead of next season. 

​Havard Nordtveit has already agreed a deal to join West Ham from the Bundesliga this summer, but here are three other players Slaven Bilic should keep an eye on in the upcoming transfer window.

3. Cuco Martina

Right-back is undoubtedly a position Slaven needs to address this summer. Carl Jenkinson was considered first choice at the start of the season, but poor form saw him drop behind centre-back James Tomkins in the pecking order.

Injuries to Tomkins and lately Joey O'Brien has seen Michail Antonio cover at full-back. If West Ham are to push on next season, they will need the goalscoring talents of Antonio further up the field, meaning that a right-back is needed this summer.

West Ham did sign Sam Byram from Leeds in January, but injuries and suspensions have limited the 22-year-old's appearances and many believe that he is a player for the future, instead of a first-team starter.

Cuco Martina is a worthy candidate to be signed at right-back; the 26-year-old signed for Southampton last summer but found himself behind Cedric Soares, meaning he has played just ten times in the Premier League. One of those was against Arsenal on boxing day, where the former FC Twente man opened the scoring with a wonderful long-range strike in a 4-0 win.

He has pace, defensive discipline and the ability to attack and he could be a prime candidate for Bilic this summer.

2. Gokhan Tore

​​Bilic has been a keen admirer of Gokhan Tore since his days at Besiktas. West Ham attempted to sign the 24-year-old in January but were stumped by Besiktas' hefty asking price. 

However, with the upcoming move to the Olympic Stadium in sight, owners David Gold and David Sullivan have announced they will spend big in the summer. 

Tore is a tenacious winger who can play on either side of the midfield. Besiktas' vice-president Ahmet Nur Cebi revealed this week that a fee of around £25m would be enough to prize the Turkish international to the Premier League, a fee that West Ham are likely to reach.

1. Michy Batshuayi

Earlier in the season West Ham owner D​a​vid Sullivan announced that the club were looking to make a marquee £20 million signing ahead of their move to the Olympic Stadium. The claims came before Andy Carroll surprised us all by scoring a hat-trick in the 3-3 draw with Arsenal, but the point still stands - West Ham are in the market for a striker this summer.

The Diafra Sakho situation is ongoing, the Senegalese striker missed last weekend's tie after allegedly falling out with Slaven Bilic. According to ​West Ham Way, Sakho has received interest from a 'well-performing' side abroad, meaning that the 26-year-old could be on his way out at the end of the season.

Bilic played down speculation linking the Hammers to Zlatan Ibrahimovic, who will be a free agent in the summer once his contract at PSG expires. Another name linked is Lyon's Alexandre Lacazette and while this would undoubtedly be a great signing, it's likely that the interest of Tottenham and Liverpool will beat the Hammers to it.

​So that leaves us to Michy Batshuayi, who played alongside Dimitri Payet at Marseille. The 22-year-old Belgian striker has managed 14 goals and nine assist in Ligue 1 this season and could be the perfect man to fill West Ham's gap up-front. 

Batshuayi is a powerful striker that would seemingly be well suited to the Premier League. He has pace, a ferocious strike and has linked up well with Payet in the past. 

​If West Ham do sign the Belgian, he will act as suitable competition for Andy Carroll while bringing the clinical striking edge required to take West Ham to the next level.
