Celtic are one of the biggest and most successful teams in Scottish football history and over the years they have been blessed with some of the talented players that the game has had to offer such as Kenny Dalglish, Henrik Larsson, Jimmy Johnstone and many more.
However, a key factor in the team’s success over the years has not just been their technical ability and flair, but also their ability to battle for every tackle, fight for every win and ultimately overpower their opponents.
When all else fails, the ability to be physical and grind out results can often be the key to victory and the Hoops have often been blessed with a number of no-nonsense tough tackling enforcers that have been able to win their individual duels across the pitch.
