Aaron Ramsey will leave Arsenal in the summer after over a decade in north London.
The Welshman arrived in the capital from Cardiff back in 2008 after rejecting a move to Manchester United at the last minute.
Since then, Ramsey has overcome a serious leg-break at Stoke to become one of Arsenal's most important players.
The 27-year-old has scored the winner in two FA Cup finals and is the highest scoring midfielder in the Gunners' illustrious history.
So why are they letting such a great player leave during his peak years? It's certainly a baffling one.
Arsenal are not willing to match his lofty wage demands, while Unai Emery doesn't seem to have too much faith in the enigmatic midfielder.
But how do Arsenal go about replacing him? Well, according to Peter Crouch, it's going to cost the club an arm and a leg, with the Gunners already lacking in funds for transfers.
Writing in his Daily Mail column, Crouch said: "Arsenal, clearly, have made their minds up, but they also made a rod for their own back when agreeing to give Mesut Ozil such a huge new contract 12 months ago.
"That is the benchmark wage and every player in the dressing room will know how to push their own negotiations.
"It will be Arsenal's loss when Ramsey goes because it will cost them a fortune in terms of a transfer fee and wages to find someone of comparable ability.
"He, however, will look at it as a great opportunity and a new start will give him a new lease of life."
In the current transfer market, Ramsey's value - if he were tied down to a contract - would be way over the £50m mark.
That's pretty much what Arsenal will have to spend and it may be even more if they want to bring in someone younger.
For Ramsey, he's getting the chance of a lifetime in playing with Cristiano Ronaldo at Juventus. Arsenal really do look like the losers in this scenario.
