But... why?
Gyokeres absolutely tears it up in the Portuguese league and comes in for £60m, which apparently Arsenal are still trying to negotiate down. But Arsenal are willing to pay Chelsea £52m for a player Chelsea doesn't even want? The English Tax explains some of it, but even though he's English he doesn't even count as homegrown.
If this were an end-of-the-window thing and all the other players we were after had already been signed, or we'd missed out on them and had to settle, then I could see it. But, that seems like a lot of money for a player who, if he's behind Saka, won't even be a starter. If they're buying him as a left winger, why buy a right winger to play on the left?
If they are buying him to play on the left, does that mean that they're not going to sign Eze? He's actually a left winger, he's actually better than the current starters, and would only cost an extra £20m?
Maybe if you're hoping to win the CL, you need to be buying £50m players who won't start. But, wouldn't it be smarter to buy a £70m who will start (and counts as home grown) and then have someone like Martinelli as the backup?
The fact he's from Chelsea doesn't really bother me, except that it means that Arsenal are helping Chelsea to meet their FFP obligations... not that those actually seem to matter.
