It’s agonising to think of what might have been but, if we’d beaten Crystal Palace at the weekend, we’d probably need five points from our last four games to clinch a top-four finish.

Whichever way you slice it, we’ve made life more difficult for ourselves. But our destiny remains in our own hands and a third consecutive away win would give us some breathing space.
‘One-nil to the Arsenal’ was sung long and loud at Watford and Napoli - how we’d love another one of those tonight.
