According to Dutch media outlet De Telegraaf, Southampton attacking midfielder Dusan Tadic could be on the verge of joining Eredivisie giants Ajax.

The Daily Echo reports that the 29-year-old is keen to leave the south coast outfit this summer after four seasons at St Mary's, with the club only narrowly avoiding relegation to the Championship last term following a difficult 2017/18 campaign.

The Serbia international played a key role in helping Mark Hughes' men survive with three goals in their final six Premier League fixtures, but in general he has endured two difficult seasons following two successful opening years with Saints in which he was one of their biggest threats in the final third in terms of goals and assists.

The attacker will leave a huge void to fill once his exit is confirmed, and Hughes will surely look to scour the transfer market to try and find a player that can make an even bigger impact than him.

Here are three Tadic upgrades Southampton should target this summer…

If Hughes is looking for a player that can not only bring a creative spark to his side, but also a big goal threat, he should look no further than Basel attacker Elyounoussi.

The 23-year-old, who usually plays as a No.10 or on the left wing, enjoyed a brilliant 2017/18 campaign for the Swiss outfit, scoring 13 goals and providing a further 17 assists in 44 appearances in all competitions, including a goal and assist in his side's 2-1 win against Manchester City in the Champions League in March.

While the Norway international has three years left on his contract, he could be available for a reasonable fee that is affordable for Saints.

Sao Paulo attacking midfielder Cueva has proven just how good he is for Peru at the 2018 World Cup, and while he did miss a penalty kick in his nation's 1-0 defeat to Denmark in their opening group game, the skill, pace and technical ability he showed throughout suggests he can make an impact in the Premier League.

The 26-year-old is energetic and causes constant problems for opposition defenders, and while bringing him to St Mary's for his first ever spell in European football would be something of a risk, he has shown that he has the attributes to make a real difference for them in the Premier League.

The Croatia youngster burst onto the scene with Dinamo Zagreb when he was 16 years of age, and he impressed so much that Barcelona snapped the youngster up in 2014.

The 22-year-old has struggled to really fulfil his potential since then making just one first-team appearance for the La Liga giants before loan spells Sporting Gijon and Las Palmas following a permanent move to Hamburg in 2016.

The midfielder has the ability to be the new Luka Modric before of the technical qualities that he has, and two goals and two assists in 20 Spanish top flight appearances for Las Palmas last term show that he is ready to make an even bigger impact.
