Buendia and Coutinho in an emergency.
Don't see how we fit another attacker in there unless some of them are leaving.
To be fair, Levante only got relegated in the 2021-22 season, before relegation they had been in La Liga for 5 seasons in a row. I have no idea if this player is the best young full back in the world, but I'm sure Emery and Monchi would be aware, so will trust their judgement if links are true.
Seems to be concerns from some if he can step up from Championship to PL, we will never know unless we try him there or loan him to another PL club to test him there.
The danger as well is the player becoming disillusioned with being constantly loaned out. As you say, there needs to be a pathway for these young players.
