The 23-year-old started his career at Real Madrid and rose through the youth ranks, being handed his La Liga debut by former boss Carlo Ancelotti in 2014. However, last summer he was allowed to leave the club and opted to join Ponferradina, scoring six goals in 42 matches as the northern Spanish outfit finished seventh in the second division.
His performances at El Toralin have impressed onlooking Manchester City scouts, prompting the club to sound out a deal which is expected to be completed within the coming days.
But there could be one potential snag involving Real Madrid as the Santiago Bernabeu outfit have a buy-back clause and are said to be mulling over the option of re-signing him.
"Former Real Madrid Castilla player Rubén Sobrino will sign for Manchester City in the coming days if the Bernabeu doesn't exercise a buy-back option on the forward," AS report.
One for the future:
Despite being a little bit older at 23, Sobrino is still widely regarded as one for the future as the forward possesses plenty of potential. He can be described as a creative forward, one who is willing to drop deep, link up play and create chances rather than a natural-born striker who only has an eye for goal.
If Madrid opt against re-signing the striker, they will receive a nominal fee for him, while reports in the Mirror are already citing a possible loan switch from Manchester City back to Spain through Girona.
