A 4 - 0 win for Arsenal in the Carling Cup against Newcastle saw Theo Walcott score two good goals which required calmness and composure in front of the opposition goalkeeper. The goals also required his blistering pace, as well as the ability to hold his run to stay onside. His goals helped to create a confidence for Arsenal to go on and win the game very comfortably with a young team, as well as giving him the confidence he needs to score similar goals in the future.
A footballing brain is something that Theo Walcott has been criticized for not having. He has been heavily scrutinized by critics who say that he doesn't know what to do with the ball in the final third of the field - an area in which he should be oozing with quality considering the very attacking position he plays. However, against Newcastle, he showed great improvement. They may not have had their first choice defenders in the team, but Walcott waltzed through the Newcastle back line, chasing through balls from his team-mates who know that the England International is willing to run.
The two goals he scored were very clinical. He needed to keep calm and out-wit the out-rushing goalkeeper. He did that, and after picking his spot, made sure the ball rippled the back of the net with a nice dink over the goalkeeper in the first instance, and then powerfully side-footing in the second. His role against Newcastle was a much more central role than what he normally plays, which is probably why he got those one-on-one chances against the goalkeeper. But he showed that he is capable of scoring goals under pressure in that position, and now all he has to do in master crossing the ball.
He has the pace, and now he has the composure, but out on the right wing, when strikers are hungry for a delicious cross into the box, the winger has to deliver. Walcott finds it hard to find the right man with his crosses, which can frustrate the fans as well as the waiting strikers. He must improve. More hours practising on the training ground, persistence and hard work - whatever it takes, because it is this feature of his game (as well as other small factors) that makes him a good player with potential rather than a great player with quality.
