For me this screams media fabrication, it's what happens for every big transfer.
Remember how Di Maria was off to Tottenham too?
Yes, but I didn't buy that, and it was because Spurs were never linked with di Maria prior to the Bale links to Real started going around, this though is different, Sanchez had been consistently linked with Pool prior to the Suarez links to Barca started to pick up.
And with di Maria, I'm positive at some point Spurs wanted him part of the Bale deal (with lesser money) and he shot it down, which there's less of a chance of happening with Sanchez because if the reports are to be believed, Pool have already had talks with Barca and Sanchez about a possible move to Pool, among other clubs.
Ofc, he could always prefer a move to somewhere else like Juve, but I'm not sure they'd be willing to be pay up, then again, are they really after anyone else? I'm not even sure they need to strengthen anywhere else, maybe a replacement or something if they offload a player, but they'd obviously have money from the sale to work with.
