COMMENT: Last week it was announced by agent Ali Bulur that his client, Shkodran Mustafi, would be set to leave Valencia during the summer transfer window.
But one question remains – why hasn't a big club come in for him yet?
The departure of Mustafi, who reportedly has a €15million release clause, would certainly be a big loss for Valencia as the German will be a tough man for the La Liga side to replace.
It's a shame that Mustafi will be leaving Valencia during the transfer window, due to the fact that he has been at the club for only two years and has prompted many Los Che fans to forget Nicolas Otamendi.
Otamendi was the last centre-back that left Valencia for a Premier League side. The Argentine had a tough time settling in England, but has now been a key player at Manchester City.
The 24-year-old will definitely think of a transfer as the right choice to increase his development and aim for success – with Valencia finishing just 12th last season.
It's not a surprise that Mustafi's name has been brought up in the media as his performances are recognised by many which brings about the links with other clubs in Europe.
With the limited resources Barcelona currently have, Mustafi would have been the perfect signing for the current Spanish champions. The Blaugrana have snatched a few of Valencia's players over the years - such as David Villa, Jordi Alba, and Jeremy Mathieu - who have since played their own part in Barcelona's success.
Barcelona prefer to buy most of their defenders from the Spanish league and have done so for quite some time, but with the announcement of young Frenchman Samuel Umtiti, who has joined from Lyon, it's very unlikely that Luis Enrique will bring in another centre-back this summer.
Valencia's number five was fantastic in La Liga in 2015/16, but despite his best, no progress was made under Nuno Espirito Santo or his replacement Gary Neville, who was sacked after being in charge for just four months.
The centre-back completed 30 league appearances last season, whilst he averaged a WhoScored.com rating of 7.27, which was the highest amongst the whole Valencia squad.
Mustafi played more minutes than any other central defender from the Mestalla and finished each game with three aerial duels won.
Mustafi is known for his aerial presence, ability to intercept and is a no-nonsense defender, ensuring the ball is cleared rather than taking time on the ball in his own penalty area.
Currently the Premier League is missing some world class centre-backs, so Mustafi would be everything a top English side is looking for in a defender. Being versatile, Mustafi also has the ability to play as a right-back when needed.
Although he was at Everton during the early days of his career, he didn't get much of a chance at Goodison Park and instead, left to join Serie A side Sampdoria. Since then, he has grown into a dependable centre-half who has gone on to win 12 caps for Germany.
At international level, Mustafi is the third option centre-back for Germany; just behind Jerome Boateng and Mats Hummels, but he made his debut during a friendly match a few months before the 2014 World Cup and went on to being selected by Joachim Low for the competition.
However, a move to a club that's currently in a better state than Valencia will surely lead to more appearances in the shirt of his national team.
Currently it's been reported that Mustafi has received a couple of offers from Italy, which would make it very interesting if the defender was to return to Serie A after being part of a Sampdoria side which he helped return to top flight football at the age of 20.
Whatever happens this summer, it will be no secret that Mustafi will be wanted by many teams in Europe and he will definitely decide the right move in order to pick up some success during his career.
