Yes. But what happened with all of these players? We got rid of them. Sorry, but you can't ignore the fact that he is getting paid 50-60k every week to sit on the bench. You just can't. We're Southampton, not Chelsea.
Simply put, you have to ask yourself, "would Ramirez be in my starting eleven next week against Man City?" - The answer for me is "no". And the answer for Pochettino will also be "no".
Saying all this though, I'm still willing to give him one final chance; We have seven games remaining, with relatively little to play for. Ergo, throw Gaston in at the deep end and give him 2-3 full 90 minutes to see what he can do. And tell him directly; "Final chance, no excuses!" If he is able to impress - not just with pretty flicks etc - but with actual genuine work rate and commitment etc, then happy days. but anything less than this, then its time to get rid. And yes, we could definitely find a decent replacement for the recouped fee/wages.
