This summer saw Leeds United sign a player from Barcelona. Whilst it was not one of their stars, it was still an eye-catching grab.
Leeds secured the signature of the 20-year-old in July after his contract at Barcelona had come to an end.
Mujica had spent the previous season in the Barcelona B team, where he scored seven goals in 33 games. That included a hat-trick in a 3-0 win over UD Conquense, where he faced former Leeds United talent Oriol Rey.

But Mujica was near immediately sent out on loan to play regular first-team football. He joined Spanish second-tier side Extremadura on a season-long deal but it has not yet taken off.
Extremadura are struggling at the wrong end of the table, just four points off the bottom spot currently occupied by fallen giants Deportivo La Coruna after 13 games.
Mujica, has barely played a part. After initially struggling to get in the squad, playing just 43 minutes over three substitute appearances, the youngster has not played since the 1st October because of an injury problem.
Leeds have plenty of talented young forwards in their ranks, including Ryan Edmondson and fellow Barcelona alumni Kun Temenuzhkov.
If Mujica wants to put his name on the Leeds first-team radar for next season his experience out on loan needs to improve.
