Manchester United boss Solskjaer paired Rashford and Lukaku in attack for Tuesday’s game against Burnley at Old Trafford.
However, the experiment to play the duo together backfired with the Clarets emerging from the showdown with a point to their name.
Burnley had Manchester United facing a first defeat of the Ole Gunnar Solskjaer era when Ashley Barnes and Chris Wood found the net.
But the hosts rallied through Paul Pogba and Victor Lindelof to secure a draw.
United fans on social media were not convinced by Solskjaer’s experiment, criticising the decision to play field both players in attack.
Yet the 45-year-old has defended his decision, insisting it only didn’t work because it ‘was not Lukaku’s day’.
“Rom’s done really well against Burnley before,” he said.
“With Anthony injured we thought it was the best option with Rashy out there.
“He had a couple of chances but it wasn’t his day.”
Lukaku has lauded Solskjaer, saying that life under the United boss is ‘different’ than before.
The Norwegian has injected positivity into a side saddled by the negative of Jose Mourinho.
“We’ve not had the chance to do proper work on it yet,” he said.
“But just having those words around you it makes a difference.
“I just want to keep improving on that.
“It’s totally different. Marcus and I and Anthony (Martial) and all the rest are learning a lot from him, especially on the offensive side.
“You have to be ready, that’s what the manager told me before the game.”
