We fell behind 20 minutes in when United split us open with a cross-field ball and Joe Riley converted, but we made our control of the game count with a fine reaction and finish from striker Harrison 11 minutes later.
With Charlie Owens marshalling the back line with real desire, we gave ourselves a platform to push on in the second period and it was all Spurs after the break.
Kyle Walker-Peters and Harrison – twice – had chances to win it but United were able to close ranks and it finished 1-1, yielding our first point in six games in this competition.
