Ramsdale is a very good goalkeeper. He is capable ot top quality saves which he has no right to be saving, he's shown that many times in his time at Arsenal.
And he's a big personality, that's obvious.
Good on set pieces, good communicator etc etc.
But, and this is pretty fundamental, he is completely average shot stopper most of the time. In 1v1s he just doesnt save often enough for me. How many times would say Kane score if clearn through on goal with him? 80-90%? That's the reality and you just dont back him in the 50/50s.
Finally, his penalty stopping is a complete disgrace. He is nearly as bad as Lloris/De Gea which is saying something....
Frankly, we've outgrown him. He's very much a top/4-Europa League level keeper. So I would have no issues replacing him, as popular as he is.
Hes not improving, he'll be at this level now until he's finished. That's where we are with him.
You go through our squad now. Saliba/Rice/Partey/Odegaard/Saka and there is quality everywhere, literally. Except GK where we're just "good" so its the obvious place to add quality. We didnt expect to be in this position but we are.
Raya is not an upgrade however, and has been around the block a while now.
Personally, I think Ramsdale is "OK" for now and wont be a calamity keeper ever. He's just not top top level and the 3-4 points a season we might gain from an upgrade is probably worth the £60m we'd spend on genuine top class.
So I would wait until a top top class GK comes around. Liverpool did this with Becker and benefited hugely and we're in a not dissimilar position. I dont want an upgrade on Ramsdale just, which frankly is easy to do but a waste of time. We should be scouting and as a "generational" GK, as soon as a Becker/Oblak/Cech/Neuer appears, we should pounce. We can get £30m for Ramsdale and if we upgrade and get a #1 that'll be around for the next 10 years then it's a no-brainer. These level GKs appear fairly regularly and we shouldnt have issues attracting them so lets just wait it out.
The teams that win the title all have top goal-keepers, with the exception of maybe Joe Hart and DDG. In 25 years the list is Seaman, Schmeichel, Cech, Van Der Saar, Becker, Ederson. Ramsdale is a level below that. Just the way it is.
