These are the same conversations we have had with all our midfielders seemingly on rotation.....Santi, Ozil, Rosicky.....and many were suggesting not too long ago that Cazorla was very expendable and even that his career at the top level was finished. Certainly at Arsenal. Look at him now. As far as I'm concerned he is a world class player.
That's not to say we should keep them all indefinitely but relatively young players who are clearly talented should not be let go at all easily, regardless of the fact we have better options at this exact moment in time.
I think when he has been fit, Jack has been very good this season. He tends to punctuate games with a few silly moments which overshadow or mask the fact he has actually played well and then he exacerbates things further by getting caught with his pants down off the field and sprinkles various injuries on top to finish which further stokes the ire of many fans. All of it goes a long way to obscuring the fact he has been good even during the times when few others were playing well around him this season.
If he wants to get in the side he will need to raise his game and get serious off the field and I want to see him rise to the challenge rather than just seek the first bus out the club for him.
