Turan, 27, made his name as a youngster with Galatasaray, who he joined aged just eight before captaining the side from 2009 until his move away in 2011 to Atletico Madrid. The Turkish winger joined up with the La Liga side for around €12m, and having established a strong reputation during his time with Galatasaray, it was no surprise to see him excel in Spain.
As Atletico have embarked on an incredible season which has seen them lift the La Liga title for the first time in almost 20 years as well as reach the Champions League final, Turan was a key member of Diego Simeone's team, playing an important role out wide to supply star striker Diego Costa with the ammunition to score goals.
Yet as is the case with Costa, his impressive displays have led to interest from elsewhere, and Turan has been targeted by the likes of Arsenal, Liverpool and Manchester United in recent months, with the latter even choosing to cancel a deal to sign Turan in order to bring Marouane Fellaini to the club instead - which was of course a huge mistake.
It now seems that the Red Devils have missed their chance with Turan, as reports in Spain suggest that Barcelona have agreed to pay £33m in order to trigger Turan's release clause - but United can still benefit from the deal if it does indeed go through.
Turan's arrival would create something of a logjam out wide for Barcelona. The return of starlet Gerard Deulofeu from his Everton loan spell has already added another dimension, whilst Neymar, Alexis Sanchez and Pedro are also in the ranks and will be expecting to feature heavily.
It's Sanchez whose future will be of most interest to the Red Devils. Louis van Gaal's men are already reportedly in talks over a £20m move for the Chilean international, and if Barcelona are close to tying up a deal for Turan, it may suggest that Sanchez will be allowed to leave the club - and with an injection of pace and quality desperately needed on the flanks at Old Trafford, United could even end up with the better side of these transfer situations.
