United broke the world transfer record to take Pogba back to Old Trafford, four years after selling him to the Italian giants for just £800,000.
Bilic told the Hammers' website: “If we could have Pogba we would sign Pogba, make no mistake.
“But I would be the first to say, ok, if everybody cuts, let's cut. It is crazy, it's way too crazy.
“But it is big-game fishing and for that you need tools. You can't expect to get the shark with a small fishing rod."
