Concentrate

If Bob and Caley played football they would probably both be goal keepers of very contrasting styles. Bob always comes of his line and grabs the ball with confidence. Caley prefers to stay on the line relying on speed and agility to snatch the ball. It’s up to the pundits to discuss the merits of each approach but very seldom does a ball get past either boy such is their intense concentration on the game.
However they both risk yellow cards at times as they can be very reluctant to give up the ball when the whistle blows for a foul.
