Fair play to Leicester winning the league a few ago, this gave them a winning mentality and the core of their team (Schemeical, Morgan, Albrighton, Vardy etc etc) give the belief to the other players, hence todays performance.
It gave them such a winning mentality that they went out weakly in the CL the next year, finished 12th, 9th, 9th the 3 years following it, went out to Slavia Prague in the EL and now finally lucked out on a trophy 5 years later.
If the VAR goal had counted would that mean they hadn't got a winning mentality? Was it the mm's that Chelsea was offside due to their winning mentality?
