West Brom found themselves on the wrong end of yet more VAR controversy in their clash with Southampton after a goal was incredibly ruled out for offside.
Mbaye Diagne steered home a close-range header to edge the hosts into the lead at the Hawthorns - but a lengthy check by the technology then chalked it off.
Replays showed Diagne apparently onside, however, despite the linesman's raised flag, and it was soon revealed that VAR were unable to 'draw a definitive line'.
The explanation behind the decision was given to Sky Sports during the first half.
