Sebastian Mila is a Polish midfielder who was born in Koszalin, Poland on 10th July 1982. Mila began his career with Gwardia Koszalin, and first made a name for himself in 1999 when he represented his country in the FIFA U-17 World Championship in New Zealand. Mila then had spells at Lechia Gdansk and Wisla Plock before signing with Groclin Grodzisk in 2002. It was his form with Groclin that earned him his first cap for Poland in 2003. On 6th November 2003 Mila scored an equaliser at The City of Manchester Stadium in a UEFA Cup tie against Manchester City, which eventually sent Groclin through to the next round. Just over a month later he bagged his first goal at international level in a 4-0 win over Malta. In 2005 Mila joined Austria Wien, but enjoyed a turbulent spell in Vienna. He was selected in Poland's 2006 World Cup squad, but didn't receive a single minute of playing time.
In the summer of 2006 Mila had a trial at Southampton, and scored in a friendly match at Cheltenham. Bizarrely the club didn't announce the name of the former Groclin man, who was simply known as 'the mystery trialist'. Despite performing well at Whaddon Road, Mila wasn't offered a deal and ended up signing for Valerenga of Norway. After spending a year in Scandinavia, the Polish international returned home in early 2008 when he signed for LKS Lodz on loan. Later in the year Mila penned a four year deal at Slask Wroclaw. He helped the club win the 2009 Ekstraklasa Cup, and was also part of the team that finished runners up in the league championship in 2011.
