The England international has been working diligently since joining the club in the summer, both in training at Carrington and during his 15 appearances in matches across all competition, yet a goal involvement had not arrived until this week.
Sancho started the game on the right wing and was a lively presence at Estadio de la Ceramica, showing his cage-football traits with some nimble footwork and decisive movements.
That was never more evident than in the 71st minute when he burst inside and played a one-two with substitute Bruno Fernandes, before twisting past his marker and seeing a shot brilliantly saved by the goalkeeper.
Then came the reward for his hard work in added time, with an emphatic finish into the top-right corner to conclude an impressive team move and secure our qualification to the Champions League knockout stages with a game to spare.
Make no mistake, it was a significant moment for Sancho.
