Jose Mourinho's troubles as Manchester United manager continued on Saturday as he was sent off into the stands at half-time during his side's frustrating 0-0 draw with Burnley at Old Trafford.
Mourinho was punished by Mark Clattenburg for protesting too vehemently to the officials when United was denied a penalty after Matteo Darmian had been caught by Jon Flanagan's trailing leg.
In the match itself, keeper Tom Heaton was the hero as his saves frustrated Manchester United and earned Burnley their first Premier League away point of the season while it left his former winless in their last four league matches and eight points adrift the top.
Heaton dived to palm away a Jesse Lingard header and spread himself to block a powerful Zlatan Ibrahimovic volley against a United side who finished with 10 men as midfielder Ander Herrera was sent off.
He had already made a couple of straightforward stops from Ibrahimovic and Juan Mata when he raced off his line to block the former Sweden forward, who had latched onto a well-judged through pass from the Spaniard.
Burnley, whose defence included another United academy graduate in Michael Keane, were well organised as they frustrated the home side.
But they were indebted to Heaton as United started to find gaps in the later stages of the first half.
He dived to his right to push the ball aside after Mata had dug out a left-foot shot from the edge of the penalty area.
Heaton was grateful to see former Manchester City defender Ben Mee throw his head in the way of Ibrahimovic's shot after a lovely drag-back flick from Paul Pogba set up the chance.
But the England international was inspired as he palmed away a powerful Lingard header from Herrera's right-wing cross, before tipping over a 25-yard Pogba drive moments later.
Heaton stopped Mata's close-range shot from an Ibrahimovic cut-back, then got his body in the way bravely to block the Swede's thunderous volley.
When Mourinho's side beat the goalkeeper, they were still denied, as Mata hit the post with a clever shot on the turn and Ibrahimovic looped a header against the bar.
United then lost Herrera to a red card. The midfielder, booked for a first-half foul, was shown a second yellow card and sent off for a late challenge on Dean Marney.
Wayne Rooney, back from a thigh injury, appeared as a substitute for the final 17 minutes, but could not inspire a victory, blasting over from Daley Blind's low free-kick deep into stoppage time.
