“There was a certain halfheartedness to the way Celtic manager Ronny Deila celebrated his club’s victory over Rangers after the full-time whistle, performing his now customary fist-pump routine in front of his own fans. Bragging rights don’t mean so much against such helpless opposition. The blue half of Hampden Park — the age-old, neutral battleground between Glasgow’s two bitter rivals — had emptied long before, leaving behind nothing more than the lingering air of factionalism and toxic bile that comes with every Old Firm derby. Police arrested 12 fans for alleged sectarian breach of the peace, with scuffles between supporters running into the night across the city.” Grantland
