Jose Mourinho was angry with Manchester United’s attacking players for failing to kill off their Europa League quarter-final tie with Anderlecht.
Henrikh Mkhitaryan put United in front with a vital away goal in the first leg at the Constant Vanden Stock Stadium in Belgium.
However, Leander Dendoncker’s late strike has left the Red Devils with more work to do in the return fixture at Old Trafford next week.
Mkhitaryan formed part of an attacking line-up with Marcus Rashford, Jesse Lingard and experienced striker Zlatan Ibrahimovic.

But only the Armenian could find the net in a wasteful performance from Mourinho’s attackers and the Special One was far from happy with the result.
“We have to kill matches,” Mourinho told BT Sport. “We have chances, we have control, we don’t score.
“There was lots of space to play, to kill, lots of half chances but we don’t score because of bad decisions in the last third.
“One mistake and we were punished. We have to play more seriously.

“If we put altogether the performance of all of our attacking players and you squeeze it – not much juice comes out.
“If I was one of my defenders I would be disappointed. The ones in front didn’t kill the game.”
Mourinho must now turn his attention to a huge Premier League fixture with his old club Chelsea on Sunday afternoon at Old Trafford.
Then comes the return leg with the Belgians in Manchester as United look to reach the semi-finals and secure Champions League football for next term.
