Athletic reporting it. Loan with option to buy. He'll be back in the summer.
I'm baffled by all these loans, with option to buy signings, it's hard to imagine many will actually happen. Plus it's a big risk if the player gets injured whilst on loan.
It doesn't really help the "selling" club at all, but I can see why buying clubs want them. If he goes there, and does well, they know we're not going to try and pull their pants down on the price in the summer. Similarly, they can just hand him back in the summer.
Options to buy actually mean very little, beyond setting a ceiling on any potential selling price.
