Chelsea boss Andre Villas-Boas felt scrapping the pre-match handshake was a wise move ahead of their FA Cup win over QPR.
Villas-Boas knew nothing of suggestions more than one QPR player would snub John Terry and revealed he only learnt there would be no handshakes 45 minutes before kick-off.
But despite on Friday insisting it was "extremely important" Ferdinand and Terry shook hands, Villas-Boas said: "It was a wise decision bearing in mind the expectancy that was aroused from the fact that a couple of events could happen in that handshake.
"It was wise not to do it because it could have an impact on crowd behaviour."
