Depends on Pochettino.
I suspect that phrase is the key to the summer.
That might be the key phrase to a lot of things happening over the next few weeks and months.
The elephant in the room [or the ghost in the cupboard, I think it's the former] is Poch saying it would make no sense for him to stay at Southampton FC if Nicola Cortese left. Yet, in January, several days after Cortese left, he said [quote from Guardian quoting Poch]:
"I want to show my gratitude to Nicola Cortese. I believed in him, he brought me here, my staff and my family. I am full of gratitude to him.
Eight months ago when this happened we were finishing my first season and I did say that if he left there would be no sense for me to stay.
The new situation is different. We are in the middle of our new project. Nicola knows of my decision to stay; I have spoken to him. I am fully committed to the staff, the players, the club and it would make no sense to leave in the middle of our path."
Long term managerial projects don't end after another few months when you are in the middle of one. So maybe we need not be as uncertain. Of course there is always the lure of another club, but Poch strikes me as a bloke who likes to finish what he starts. And he's nowhere near finished here. Of course, if the board start selling off his players, just as they had to at Espanyol, then I'd expect him to jump, in fact, I'd encourage it, for his sake. Be loyal, by all means, but don't be stupid.
