Tottenham Hotspur were beaten 2-1 at Wembley on Wednesday to end their Champions League campaign.
Davies' positioning for the Italians' second goal - which dumped Tottenham out of the Champions League - was questionable to say the least, allowing Paulo Dybala to race through with only goalkeeper Hugo Lloris to beat.
The Welshman has however been one of Spurs's most consistent performers this season, keeping fit again Danny Rose out of the team more often than not.
Further injury problems have restricted Rose - who was Tottenham's first choice left-back before he was struck down midway through last season - to just three appearances since Boxing Day, all of which came against lower league opponents in the FA Cup.
Nevertheless, there are plenty who would have rather seen the 27-year-old called for Wednesday's last-16 tie...
I rate Davies but there's a gap between him and Rose and days like today it costs us— Decky (@mchdecky) 7 March 2018
Danny Rose's time back in the first team is now! Davies was poor....— T-O ️ (@theofitz00) 7 March 2018
Davies was a weak link tonight , needed Rose for his pace .— Jason van-Haaren (@Jasonvh9) 7 March 2018
Oh, and for all his merits, Ben Davies is not Danny Rose. He doesn’t have the end product to compete in these sort of games.— jack phillips (@jbsphillips) 7 March 2018
Never been a massive Ben Davies fan but he should never have played over Rose tonight. His lack of pace was the cause for the 2nd goal I'd say. He made the back four stretch across the pitch as he wanted to be near enough touch tight. Huge shame for Spurs and English football— David Moore (@_DavidJMoore) 7 March 2018
Ben Davies over Danny Rose in a game of this magnitude is just indefensible— Shane (@InternetShane) 7 March 2018
I can critique Potch, he should've played Rose and Wanyama. Davies has been brilliant but he ain't no Danny Rose.— Junior Knowles (@nub1a9) 8 March 2018
Blame Ben Davies how the f can u start him over rose!!!! And not even use f-ing Lucas!!?!!!!!!!— Az/Aaron (@SLiiPZHD) 7 March 2018
The fullback situation really is driving me mad. Rose and Aurier are far superior to Trippier and Davies. Ben has done well but Rose is a world class player; he and Aurier need to be starting.— Ryan Male (@Ryan_Male18) 7 March 2018
Tottenham had taken a first half lead against Juventus, with Son Heung-min on target, but quickfire goals from Gonzalo Higuain and Dybala ensured a somewhat smash-and-grab win for the visitors at Wembley.
