Its probably a good thing for Soton that the top clubs aren't really looking for a striker (unless Kane goes to Utd), else they would be sniffing around Ings. I think they probably deserve to have a top player stay with them for at least a few seasons.
I don't think he would necessarily look to jump ship, unless there was some guarantee of being 1st choice - after all, he could've just stayed with us if he just wanted to be at a top club.
