M'Poku, 23, started his career with Standard Liege before joining Tottenham Hotspur at the age of 16 in 2008, playing for the club's youth and reserve teams.
The DR Congo international enjoyed a fruitful loan spell with Leyton Orient in the 2010-11 season, but having failed to even make his first-team debut for Spurs, M'Poku left in the summer of 2011 in order to rejoin Standard Liege.
With 26 goals in three-and-a-half years back in Belgium, M'Poku rebuild his career, and joined Qatari side Al-Arabi in January, only to be loaned straight out to Serie A strugglers Cagliari.
Now, Sport Italia believe that whilst Cagliari would want to keep him permanently, a deal is complicated, and if Cagliari suffer relegation to Serie B, there is little to no chance of a deal.
They also suggest that, if that is how the situation plays out, M'Poku could make a return to English football with Leeds United, given that Whites president Massimo Cellino still having good relations with his former club Cagliari.
M'Poku has pace and dribbling ability, whilst he would also finally offer Leeds some flair out wide with manager Neil Redfearn struggling without any notable wide players this season.
A move to Elland Road is far from a formality and appears to be just a possibility right now given M'Poku's complicated contract situation, but Cagliari's fight against relegation may be key to M'Poku's future - and any potential move to Leeds this summer.
