While Sean Dyche has spent the season complaining about penalties, his gripe was different on a day when Burnley were awarded two and allowed to take one as confusion briefly reigned at Turf Moor.
As Dyche often notes, Burnley have not been given a penalty in the Premier League since April 2017 but referee Simon Hooper twice pointed to the spot. The first decision was reversed because of VAR, with Dyche annoyed by the time technology took, but Chris Wood scored from the second to eliminate Barnsley.
Dyche's reign includes Cup defeats to Accrington Stanley, Port Vale and non-league Lincoln but, following more meaningful wins over West Ham and Huddersfield, victory completed Burnley's best week of the campaign.
Nevertheless, it was forgettable fare apart from the controversy as VAR, a 21st-century phenomenon, made its debut at a 19th-century ground. It brought bemusement on Matej Vydra's distinctly unusual afternoon. The summer signing earned two spot kicks, prepared to take one and was relieved of penalty-taking duties after neither scoring nor missing when Wood came on.
Vydra was tripped by Liam Lindsay – "an absolute stonewaller," said Dyche – when Wood drilled in the winner and was nudged over by Dimi Cavare in the first half. Vydra was starting his run-up to take the penalty until he was belatedly ruled offside when Steven Defour found him.
