Diego León

Diego León Ayarza (born 16 January 1984) is a Spanish footballer who plays as a midfielder.

Real Madrid / Grasshoppers
León was born in Palencia, Castile and León. A youth product of Real Madrid, León could never appear for more than its B-team. He was initially given a number with the main squad for the 2004–05 season, but moved to Arminia Bielefeld in Germany (first on loan) in January 2005 before he could make his official debut for the Spanish giants.

León stayed at Arminia until the end of the 2005–06 campaign, after which he joined Grasshopper Club Zürich in the Swiss Super League.

Barnsley
On 21 December 2007, it was announced that León had signed a pre-contract agreement with Barnsley, with the transfer due to go through at the opening of the transfer window. The Yorkshire club had hoped to make the move official in time for him to play in the FA Cup third-round tie against Blackpool on 5 January 2008, but had to wait until the 9th: he made his first appearance that evening, playing in a reserve team match against Sheffield United.

León put in a great performance to earn himself his first match ball as a Barnsley player, with a Man of the match award against Colchester United on 29 January 2008. He went on to play in the memorable away victory over Premier League's Liverpool in the FA Cup, and also played a key role in the Reds 3–0 win at Watford on 9 April, being involved in all three goals, including a sumptuous flick for Jon Macken to square to Kayode Odejayi to score: his corner allowed Stephen Foster to head home and his throughball enabled Odejayi to score his second.

In the following game against Preston North End, León netted a key goal in Barnsley's Championship survival in the 2007–08 campaign, scoring from a 35-yard free kick for the 2–1 triumph. His second and final goal for the Tykes came in a 3–2 win over Burnley on 24 November 2008 and, on 7 May of the following year, he was told, along with Dennis Souza, Kyle Letheren and Marciano van Homoet he was free to look for a new club in the summer; shortly after he returned to his country, agreeing a deal with Segunda División side UD Las Palmas.

Later years
On 13 December 2010, León moved teams – and countries – again, signing with lowly SV Wacker Burghausen in Germany. In June of the following year, after a failed move to HNK Hajduk Split, he joined Nea Salamis Famagusta FC in Cyprus.
