Just shut up Morten.
Yes, Carvajal is not getting any younger, he's 28, contract runs out in 2022 so he's slated for a chunky extension to wind his future down with us Marcelo-style. Seemingly anyway.
No, Carvajal is not some fucking scrub that is 10x worse than Hakimi offensively + he's light years ahead of him defensively and couldn't be replaced by him, Odriozola, young Hakimi (in 17/18) or Danilo. Carvajal sealed titles, CL knockout and final wins with his assists. His 'decline' is nowhere near where you seem to think it is. At the moment, after a relatively poor 19/20, he's part of a defensive block that is 2nd in Europe for total goals conceded.
Yes, he does need a competitor. Odriozola is somewhat of a dim lad who makes bad decisions and lacks awareness. A tryhard and heart ruling head, so not too smart it seems, but not that he's doomed. He'll probably be on loan next season and if he gets a grip, he might get another shot. Vazquez or Nacho patchwork at RB won't suffice if he's injured though.
No, Hakimi doesn't want to be a competitor. He seems to see it as 'my way or the highway' in that he wants to play. Like Marcos Llorente did. Fair play. But Real have zero reason to bin an all-time great Spanish RB to give him what he wants.
Yes, Hakimi's a great attacking option. He'd give us a lot more flexibility tactically, but...
No, he's not NEARLY a reliable defender. He's 3x as poor 1-on-1 while Carvajal has pocketed Ribery, Neymar and several others on multiple occasions. Even Bale was a better LB in his early years than Hakimi is and that appears to be the positional trajectory with Achraf. He's an athletic WB who likes to get in the box. He may or may not be a winger soon, but even in a Conte system he'll be asked to defend. In our system he'd have to PROVE he can defend before he gets time.
If he doesn't want this and doesn't care about the club nearly as much, then I'm prepared to pass. Painful as it is to lose a future asset. Especially for so cheap with no buyback as rumors indicate now.
