At over £1m, it seems a bit incredible to think Dallas could represent a bargain for Leeds, but that might yet be the case.
He was one of the best players on the pitch on Saturday, dominating the play and creating chance after chance down the right.
Even during the difficult first-half he fashioned a handful of opportunities.
It was not only going forward that Dallas impressed, as the Northern Ireland international provided an incredible level of defensive cover.
He has shown enough in the months he has played for Leeds to suggest he ranks among the club’s better players, and could end up an important player over his time at Elland Road.
