The north London side ended up only drawing with the Serie A outfit, a disappointing result considering their early superiority against Vincenzo Montella's men, but 22-year-old Townsend's contribution did not go unnoticed.
And keen to praise the winger for his display after the game was Welsh Spurs team-mate Ben Davies, who commented on Fiorentina's need to double up on the Townsend down Tottenham's right-hand side.
"He was great for us, especially in that first half. They ended up having to double up on him but he still managed to create chances for us and he had a great game, I thought," Davies told Spurs TV.
And, as statistics from WhoScored.com show, the Tottenham winger was a deserved recipient of his team-mate's kind words.
Not only did Townsend win six dribbles against the Italians but he created two chances and and took 57 touches of the ball.
The 22-year-old was also exceedingly lively in terms of crossing, attempting 11 and landing three - although he was somewhat wasteful in that regard as Paulinho landed 3/6.
Still, Townsend will have given Spurs boss Mauricio Pochettino plenty to think about with his display, which could be particularly useful for the winger with a certain Capital One Cup final on the horizon...
