Michael Olise inspired a Crystal Palace turnaround to spare Jack Butland's blushes and help the Premier League side avoid an FA Cup shock at Millwall.

Former England goalkeeper Butland's howler gifted Benik Afobe the opener as Millwall deservedly led at the break.

But lively Olise, an £8m summer signing from Reading, curled home a wonderful leveller and crossed for Jean-Philippe Mateta to head home Palace's winner.

The game was marred, however, by some unsavoury scenes off the pitch.

A section of the home crowd discernibly booed Palace players taking the knee in support of the Black Lives Matter movement before kick-off.
