Former Premier League referee Keith Hackett has called for VAR official Lee Mason to be sacked after he failed to rule out a goal which dented Arsenal’s title challenge.

The PA news agency understands Mason did not fully investigate an offside decision against Brentford’s Christian Norgaard during the build-up to Ivan Toney’s leveller during Saturday’s 1-1 draw with the Gunners at the Emirates Stadium on Saturday.
