Fans spot what Trent Alexander-Arnold did to Man Utd fans before boarding team bus as Mo Salah intervenes

Fans have spotted what Trent Alexander-Arnold did to Manchester United fans on Sunday that forced Mohamed Salah to intervene.

On Sunday (September 1) Man United suffered another humiliating defeat to Liverpool as Arne Slot's side ran out 3-0 winners at Old Trafford.

Luis Diaz scored a first-half brace to put the visitors in control, with the Colombian attacker profiting from two mistakes by United midfielder Casemiro.

The 32-year-old was hooked at half-time by Erik ten Hag, but United's fortunes did not improve as Mohamed Salah scored Liverpool's third just 11 minutes into the second half.

Trent Alexander-Arnold thought he had scored the opener when goal-line technology alerted referee Anthony Taylor that the Liverpool's full-back's shot had crossed the line.

The 25-year-old replicated Steven Gerrard's famous camera-kissing celebration, but was left embarrassed when VAR ruled out the goal for offside, much to the delight of 70,000 United fans.

Alexander-Arnold obviously had the last laugh on the pitch, but he continued to rub it in after full-time.

Footage has emerged on social media of the right-back being taunted by United fans as he made his way to the Liverpool team coach.

In response, Trent grinned and made a 'three' gesture with his hand, winding up the fans that were heckling him,

Liverpool teammate Salah walked over to him and told him to knock it off, perhaps worried that the situation would escalate if Trent continued to taunt the United fans.

Liverpool supporters were of course delighted to see their homegrown star winding up their bitter rivals.

One fan commented on X: "And people think he [Alexander-Arnold] wants to go. He's having the time of his life out there!"

Another wrote: "Trent just gets it, he absolutely despises United!"

Alexander-Arnold has entered the final 12 months of his contract at Anfield and has been linked with a move to Real Madrid.
