There are many basic areas of the game and defending you expect a goalkeeper to master. Some of the easier ones are laid out below...
1) Catching the ball - an absolute must. All good keepers, (and even the crappy ones) have got to be able to catch the ball. Especially in pressure situations, and whilst being challenged or under pressure. Not like the unfortunate incident at Anfield against Manchester City. Cost to the team luckily nothing, but a worrying sign.
2) Near post - keepers should never be beaten at the near post. No excuses. Not like the unfortunate incident against Tottenham Hotspur at White Hart Lane. Cost to the team LOST 2pts.
3) Commanding the six yard box - all keepers are expected to command the area, all should be in charge in the six yard box, and the better keepers also boss the whole of the 18 yard box. Indecision when the ball comes across the six yard box is simply not good enough. An example is the game against Bolton Wanderers at the Reebok stadium, when they scored following an innoxuous looking ball across the face of goal which I expected the keeper to deal with. Cost to the team LOST 3pts.
So here we are just three games in and already Jerzy has managed to lose an unbeleivable 5 points, if he is allowed to keep his place, and continue at this rate all season, my calculations means we will have 50 points from a possible 114. Mid table mediocrity here we come. . .
