Celtic skipper Scott Brown has spent 11 seasons at the club.

Celtic and the Republic of Ireland will play a testimonial match in honour of skipper Scott Brown later this month and, without a doubt, the 32-year-old midfielder deserves all the accolades coming his way.

The former Scotland international is in his 11th season at Parkhead having arrived from Hibernian in the summer of 2007, and he has not shown signs of slowing down.

Brown was named the PFA Player of the Year after helping Celtic to the Scottish League Cup and Premiership, and he will be looking to successfully defend the domestic treble when they play Motherwell in the Scottish Cup final on 19 May.

There is apparently still a lot left in the tank for the enigmatic character, and Hoops legend Pat Bonner believes dropping deep has helped Brown extend his career, comparing his change of position to that of Manchester United icon Roy Keane, who played 18 seasons of professional football.

“Brown is a different player now. He reminds me of Roy Keane in many ways," the legendary goalkeeper told the Scottish Sun.

“Keane had to adapt his game. He was a runner, a tackler and would score goals. He was also a snarler.

“Then Keane almost reinvented himself, he played deeper and passed the ball. He took on that personality that he was the leader of the team. Brown is very much that way. Remember when he first came to Celtic he would be up around the box."

Brown is in his 16th season as a professional footballer, and can surely go at least two more having played over 40 games this term.

He has eight league titles, three Scottish Cups and four Scottish League Cups to his name in Celtic colours.

Manager Brendan Rodgers deserves credit for Brown's form and fitness, and Celtic will no doubt miss their skipper once he hangs up his boots at club level.
