I think Saints had a very good idea of how good Shaw was and they didn't try as hard as they might of to get Buttner. As it turns out, it alerted ManU to up their interest anyhow, and it's difficult to compete against that influence, at this present time. Posters seem to forget that Saints have always given a good quality youngster a real chance at the big time, and so they did with Shaw and Ward-Prowse. In truth though, they weren't taking huge risks. Anyone can now see how good both are, and they are all the better for being given their chances early on. They'll now be real assets, next season, rather than eternal bench warmers.
One of the things that makes me love Southampton FC is that we give youngsters a chance! If the coaches really considered that Shaw was that good from the start, then fair play. But I don't think we would have been trying to sign a left back if that was the case. I truly, truly believe Fox was intended to be first choice (relegated to second choice if the Buttner deal had come off), and that Shaw was intended as backup. He just turned out to be an incredible player, while Fox continued to be poor.
I couldn't agree more about the bit in bold. They both have amazing futures to look forward to.
