Jose Mourinho likened David Wagner's Huddersfield Town side to the Berlin Wall as they defended gallantly before succumbing to a 2-0 defeat at Manchester United on Saturday.
United dominated throughout and did craft a few first-half chances, but they were largely frustrated by a dogged Huddersfield defence.
The visitors' resistance was eventually brought to an end when Romelu Lukaku turned in from close range following a fine Juan Mata cross, and Alexis Sanchez wrapped things up by burying a rebound after his initial penalty had been saved by Jonas Lossl.
Even though United ultimately won comfortably, Mourinho paid tribute to Huddersfield's organisation.
