Newcastle continue to insist that Isak is not for sale as they try - and fail - to sign a replacement, having already seen Liam Delap, Joao Pedro, Bryan Mbeumo and Benjamin Sesko all reject a move to St James' Park.

And a similar situation is unfolding over at Brentford with Yohan Wissa. The 29-year-old reportedly had a 'promise' made to him that if he stayed when Ivan Toney left for Saudi Arabia, that he could leave the following year for £27m while he had one year left on his contract.

Newcastle's star striker is willing to do whatever it takes to leave for Liverpool, but if a move doesn't happen, he'll need a way back in favor.
