Leon Best was born in Nottingham, England. As an excellent football player, he has played for many football clubs and the Ireland national football team. While in his teens, he decided to play football for Ireland that the country braised his mother. Best started his playing career with Notts County prior to become a coach of then Premier League club Southampton. In 2004, he accomplished his first professional appearance at Queens Park Rangers on his 18th birthday.
Best was also loaned to Sheffield Wednesday in the 2005-06 season, winning his first professional score and Wednesday’s first of the season. But unfortunately, the first loan spell was ended in advance for injuries, and Best returned to St. Mary’s after only five days in Sheffield. Best went back to Hillsborough after recovering with Southampton.
In August 2006, Best joined Ligue 1 Bournemouth on a month-long loan deal with an option to extend his stay. He went back to Southampton at the end of the three-month loan spell. During this time, he appeared at 15 league matches and won three league goals. In October 2013, he, along with his teammate Martin Cranie, was loaned to Yeovil Town until 22 February 2007.
In 2010, he signed a three-and-half-year contract with Newcastle United for £1,500,000. Best won his first goal for Newcastle in a pre-season friendly against Carlisle United on 17 July 2010.
