R. Keane ends career due to health issues © EuroFootball.com

After six months since leaving the "Manchester United" club, Scottish champion Glasgow "Celtic" goalkeeper Roy Keane, following the advice of doctors, decided to end his football career.

The 34-year-old Irishman, known for his fighting spirit and rough play, had been suffering for a year due to a thigh injury and finally decided on Monday morning to "hang up his boots."

"After consulting with my doctors and the club's doctors, I realized there is only one choice – to step back," the player announced on the team's official website.

He began his career at "Cobh Ramblers" team, then spent three years at "Nottingham Forest." Keane played for "Man Utd" for thirteen seasons, winning seven English Premier League titles, four FA Cups, and the 1998-1999 UEFA Champions League, but missed the final match against Bayern Munich due to suspension.

Moving to Glasgow in December of this year, the Irishman won the Scottish Premier League. Keane played 67 matches for the Irish national team, scoring eight goals.

"Roy Keane is one of the best players to grace football. It was amazing that we managed to attract him, and it was a true honor to work with him. Even in that short time at the club, Roy has helped us a lot," said Glasgow "Celtic" head coach Gordon Strachan.
