Several weeks later, though, the best thing Mauricio Pochettino can do is leave the Welshman on the bench.
Not because he is off form or the worst option for Spurs, however, but because Davies is now the club's best bet at left-back.
The north London side have a Premier League clash with Everton coming up this weekend - a side unbeaten in seven games. That clash is at White Hart Lane, where Tottenham have won just twice in six league clashes.
It goes without saying, then, that Pochettino needs to save his best players for that game. And, right now, it is a measure of how far Davies has come that he is rather important to Spurs' back four.
Or is it perhaps a measure of how far Danny Rose's stock has fallen?
The 24-year-old has endured a poor campaign so far and has been found particularly wanting when it comes to his defensive duties.
At first, Rose was praised for his willingness to get forward but, as the weeks went by, less and less Tottenham fans appeared able to stick up for him.
Although tomorrow night's Europa League clash with Belgrade is an important one - Spurs are still yet to book qualification from Group C and are behind Besiktas on goal difference - it should, at least on paper, be a much less rigorous test than the one Roberto Martinez's Everton side will provide them with.
That's why Rose should start on Thursday, with Davies saved for the weekend.
