He's definitely had a decent season, to a point, but his frailties are still clear to see. Glued to his line, poor with shots from distance, bottles balls into the box. What this season has done is highlight his close range shot stopping, which has been exceptional. He has had a lot of practice but, to be fair, it would have been more than 70 conceded without some of his saves.
Don't, therefore, think he's improved that much overall, just that this year has accentuated the positive elements of his game.
Personally, I think he'll carve out a good career, but will always struggle with the weaker parts of his game so, don't think criticism is unfair, but we should acknowledge his contribution.
Time to cash in without doubt.
