Jose Mourinho waited around for Mesut Ozil to appear, Petr Cech and David de Gea greeted each other while Nacho Monreal and Ander Herrera embraced in the tunnel.
Herrera and Monreal are international team-mates, but Neville was not impressed.
‘I think Monreal’s going to a Christening there rather than a football game,’ he said on Match of the Day.
‘I can’t imagine doing that to Martin Keown ten years ago in a tunnel at Highbury.’
And Neville continued his criticism of United and Arsenal stars writing for the BBC.
The former United star was appalled with the atmosphere before, during and after the game with Arsenal running out easy 2-0 winners.
It’s time – come on Arsenal! 🔴

Neville played in some ferocious contests between Arsenal and United, but there was very little to play for the Red Devils who are concentrating on their Europe League campaign.
Both sides look like they will finish outside the top four and Neville believes their attitudes in the tunnel said all that was need to be said about the lack of rivalry.

‘I was watching it with former Arsenal defender Martin Keown in the Match of the Day 2 production office, and he agreed that the lack of atmosphere and intensity was the most disappointing thing,’ he wrote.
‘Even in the tunnel beforehand you saw everyone hugging and smiling, which would never have happened when Martin and I played.
‘Our teams were at each other’s throats most of the time – literally on a few occasions.’
