Lionel Messi nutmegs James Milner (and leaves him on his backside) after doing the same to Fernandinho as Twitter reacts to Barcelona maestro's masterclass

Lionel Messi's brilliant nutmeg on James Milner left the Manchester City midfielder on his backside, Pep Guardiola covering his face and Twitter reacting to the Barcelona star's masterclass. 

It was Messi's second nutmeg of the match, having already inflicted the same embarrassment on Fernandinho after the Argentina captain's assist created the game's only goal for Ivan Rakitic.

'I've got my legs closed up here,' said Sky Sports commentator Gary Neville, who labelled the Milner nutmeg 'barbaric' and was among those admiring the tutorial from the world's best footballer.

Match of the Day presenter Gary Lineker settled the argument of who's better between the Barcelona star and Real Madrid's Cristiano Ronaldo. 'Messi is indisputably the greatest player ever to don a pair of football boots. Don't even attempt to argue the point,' he tweeted.

Manchester United's Ashley Young simply wrote 'Messi WOW', while Queens Park Rangers striker Charlie Austin added: 'Pep's reaction says it all.' He was referring to former Barcelona boss Pep Guardiola, sitting in the stands in awe, covering his eyes.

Liverpool defender Jose Enrique tweeted: 'If Messi played against City on his own, he would still win the game. [He] is amazing. Best in the world when he wants.' 

Stoke City goalkeeper Jack Butland echoed commentator Neville by 'watching the game with my legs closed' and Dutch manager Ruud Gullit added: 'OMG. Messi made Milner famous.'

Then there was Andre Schurrle who simply wrote 'again and again and again...' while darts player Adrian 'Jackpot' Lewis wrote: 'Messi could nutmeg a mermaid.'
