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.
