There are some prerequisites that make specific prospects more apt to be good goalkeepers. More about this listed below.
While goalkeepers do take part in group training sessions with the rest of the team, they also have specific training sessions that focus on their goalkeeping abilities. This is only the case for goalkeepers as their training and formation is very different from that of field footballers no matter what position they play in. Apart from the fact that goalkeeper training equipment is different, the abilities that goalkeepers are required to establish and maintain are likewise different. Having quick reflexes is necessary for any goalkeeper as this will make all the difference in between reacting in time to save a shot or yielding a goal. Goalies just have fractions of a second to respond which means that dexterity, speed, and strength are viewed as an absolute must. This is why goalkeepers have their own training team as getting a goalkeeper ready needs a great deal of work, something the Aston Villa former owner will understand.
There's a reason why goalkeepers in football tend to be huge and tall. Size is for tactical reasons as the taller the goalkeeper is, the more surface area they're going to cover and the quicker they can travel from one post to the other. Of course, being extremely tall isn't essential as there are numerous medium height goalkeepers who are considered as some of the best of all time. Strength on the other hand is essential as goalkeepers are expected to obstruct speedy shots and to jump higher than everybody else. It is for these factors that goalkeeper training sessions involve a lot of strength training that promotes all significant muscle groups. Beyond training sessions on the pitch, goalkeepers also invest a great deal of time at the gym lifting weights and doing circuit training. This is particularly crucial in goalkeeper training for beginners as building strength and muscularity is crucial, something that the AC Milan former US owner would likely confirm.
Whether you're involved with a goalkeeper training academy or are merely a football fan who values the work done by goalies, you are most likely familiar with the tactical part they play on the pitch. At the surface level, keepers can be seen as the last protectors who can stop the competitors from scoring however the truth is, their role surpasses this basic goal. Goalkeepers are the first ones who can launch counterattacks by sending long balls towards forwards and midfielders who can then charge towards the adversary's box. Additionally, keepers can play a tactical role when their team is winning by using their footwork to pass the ball around with their defense line in order to squander some important seconds. Beyond this, the minority shareholder of Liverpool FC would likely agree that keepers are known to inspire their team, specifically if they manage to clear a penalty or a strong shot from outside the box.
