Mauricio Pochettino’s side edged into a first half lead on Thursday night thanks to Nacer Chadli’s emphatic penalty after full-back Ben Davies was fouled in the area.
However, the Serie A side levelled in the 59th minute when Federico Bernardeschi’s deflected shot beat Spurs goalkeeper Michel Vorm in Florence.
Mason, who was named captain in the absence of Hugo Lloris, took to Twitter after the stalemate to reflect on a special evening for the Tottenham youth graduate.
Very proud moment and an honour to captain the side tonight! An important away goal going into the game at the Lane next week! #COYS
