Manchester United got back on track with a 3-1 win at Brentford on Wednesday, but Cristiano Ronaldo’s petulant reaction to his substitution cast a shadow over their first victory in three Premier League games.

Ralf Rangnick’s side were indebted to David De Gea for a superb first-half display that kept Brentford at bay before United finally sprang to life in west London.

Anthony Elanga put United in front early in the second half before Mason Greenwood and Marcus Rashford wrapped up the points.

United are the first club to record 300 Premier League away victories despite Brentford’s late reply from Ivan Toney.

They sit seventh on the table, two points adrift of the top four as they chase qualification for next season’s Champions League.

But it was Ronaldo’s grumpy response to Rangnick’s decision to haul him off in the 71st minute that could prove the evening’s lasting image.

Shaking his head and muttering to himself, Ronaldo appeared to say something to Rangnick as he brushed past him.

Angrily throwing his coat to the floor, Ronaldo pointed at his chest while his teammates on the bench nervously looked away.

Rangnick initially ignored Ronaldo before sitting next to him and patting the Portugal forward on the leg as he attempted to placate him.

The 36-year-old’s strop will raise fresh questions about his willingness to fit into Rangnick’s system after his latest underwhelming display.

United at least avoided another embarrassing result after losing at home to Wolves and letting a two-goal lead slip in a draw at Aston Villa in their previous two league games.

United revival

Ronaldo, back after missing two matches with a hip problem, was nearly gifted an early goal when debutant keeper Jonas Lossl dropped a cross at the forward’s feet, but the Bees were able to scramble clear.

Despite that scare, Brentford were hardly cowed by United after beating Arsenal and drawing with Liverpool at home earlier this season.

Originally scheduled for December before a coronavirus postponement, Brentford had been made to wait for their first league meeting with United since 1947 and they played as though determined to make up for lost time.

Thomas Frank’s fired-up team went close through Bryan Mbeumo, whose low shot forced a fine save from De Gea before Vitaly Janelt’s close-range effort was blocked by Alex Telles.

Brentford were well on top and Mads Bech Sorensen saw his strike deflected into the side-netting off Bruno Fernandes.

Toney tore through United’s defence, setting up Mathias Jensen for a shot that was well saved by De Gea.

United could not have been any worse in the opening period, yet they played with far more urgency after the interval.

Ronaldo nearly gave them the lead when he met Fernandes’ cross with a looping header on to the bar.

It was a warning Brentford failed to heed and, after Toney headed straight at De Gea, Swedish teenager Elanga made the hosts pay for their profligacy in the 55th minute.

Fred clipped a pass into the Brentford area and Elanga knocked the ball up in the air before heading past Lossl from close range.

Elanga’s first goal this season changed the mood completely and United struck again in the 62nd minute.

With Brentford appealing in vain for offside, Fernandes surged on to Ronaldo’s chest-down and slipped a pass to Greenwood, who slotted into the empty net for his first goal in seven games.

After Ronaldo’s temper tantrum, it must have been a relief to Rangnick that Rashford, on as a substitute, notched United’s third goal with a fine finish from Fernandes’ pass in the 77th minute.

Toney scored from close range on 85 minutes but it far too late for Brentford.
