Watching a young Sanchez, the first impressions was he was going to be tall and athletic. By the time he went out on loan he would have been close to his ful height, but he was like a bean pole. The change in body shape is especially challenging for a goal keeper, as it affects your balance, so the odd mistake in this period is understandable.
Fast forward to this season and the Chelsea friendly was his lucky break in more than one way. Maty Ryan played the first half and Christian Walton started the second half and was expected to be Ryan's main challenge. Walton started nervously and after 10 minutes dithered with the ball at his feet, got tackled and bust his ankle.
Sanchez would not have been expecting to play that day, but came on as calm as you like and put in a confident performance.
I suspect the first time Ryan was dropped was a disciplinary matter, based on nothing other than speculation as to who the second player was involved in a training ground punch up. Would a fit Walton have got the nod that day? We will never know.
Playing an inexperienced keeper once is fine especially if you know he has already faced Man Utd (with Rochdale) and Chelsea and not been phased. The braver decision I think was giving him a run of games. It has paid of handsomely for Potter. If Sanchez suffers a dip in form, there is plenty of evidence now he is a bloody fine keeper and I think most fans will give him the space he needs to play himself back into form.
Sanchez is so obviously superior to Ryan, that you have to wonder why didn’t get in sooner.
I watched Ryan and thought - if they get it on target they score.
With Sanchez I think - whatever they do, they probably won’t score.
Top drawer keeper.
