I do worry about selling Pogba. Everyone remembers how we sold Zidane and got Thuram, Buffon and Nedved. Zidane was the most expensive player at the time and we bought the world's best goalkeeper (at the time), arguably the world's best defender and a top 5 attacking midfielder.
Even if we assume that Pogba is worth 100m. A top 5 defender, midfielder or striker would cost at least 45m. Thats because Zidane was the world's best player whereas Pogba is the world's best youngster and arguably top 5 midfielder already.
If you look at the track record of teams who have recently sold their best player and re-invested the money in 2 or 3 other players, they have not really had much success. Look at what happened to Borussia Dortmund (after selling Gotze and then Lewandowski); Tottenham after selling Bale, Liverpool after selling Suarez etc.
However, I do agree that Juve do not rely as much on Pogba as Liverpool relied on Suarez or Dortmund relied on Gotze or Tottenham relied on Bale.
My biggest fear of all is that we sell Pogba for 100m and the Marotta buys a lot of 2nd rate players and spends no more than 30m on any single player.
In the end, it will be Pogba who forces the transfer rather Marotta looking to start an Auction.
I am also not 100% sold on the idea of Cavani and Verratti in exchange. Verratti is a very good player but he is not world class. Cavani is a great player but his market value would be close to EU50-60m. Suarez is worth over EU60m.
The team is likely only to be BETTER if we sell Pogba and SPEND to upgrade (assuming someone is willing to value Pogba at 100m).
So this would be an idea for instance: SELL: Pogba (100m) & LLorente (15m?); BUY: Cavani (55m) + Suarez (65m). Net spend close to zero.
But all of a sudden we would have a world class X1: Buffon-Lichsteiner, Barzagli, Chiellini, Evra-Vidal, Pirlo, Marchisio-Suarez, Tevez-Cavani
Pulling this off will be hard though. Suarez cost Barca around 90m! But you see my point - bloody hard to upgrade the team unless you spend big $$ with that Pogba money
