The Reds goalkeeper made his first appearance for the club since his summer move from Belgian side Royal Antwerp, and played a big role in securing United's first clean sheet of the season.
His contribution on the afternoon was recognised by the fans in the stands and, since then, Lammens has been picked by supporters as our Man of the Match in the poll on ManUtd.com and the United App.
The 23-year-old garnered a majority 29 per cent of the vote for a strong all-round performance between United's sticks, which featured a notable save either side of half-time.
