I don't think so, of the clubs you name the only ones we've sold directly to are Chelsea and Villa, obviously Arsenal as well, the only one seen as a serious rival at the time would have been possibly Chelsea and I think the club knew Sterling was well off his best. Arsenal might only be the experience of this season and one or two players away, can't see us supplying them with a player as good as Laporte.
Probably irrelevant though, I think he'll want to go back to Spain. The big 3 there would all be interested as well.
