Sanchez has also just turned 24 and has 1 normal PL season under his belt and 1 weird as fuck one.If that's the case then I guess we could do worse, but I think we need a Cb with some zip in their legs as well because as much as I liked the TA/JV pairing, two good, composed brains, there were times when those two got spun too easily. Sanchez's redeeming feature is that he's got that zip, and he's not a bad defender, it's just a shame it's attached to a package that has some other technical flaws.
For comparison, at 24 Toby was still trying to crack the lineup at Atletico and Jan was still at Ajax.
Giving up on Sanchez so early would be foolish. What he lacks is some polish in the mental side...and that comes with age and experience.
