A Frank Lampard hat-trick and a brace from England striker Daniel Sturridge secured the Blues a victory at the Reebok.
“You could stay here all day talking about the good things we did, finally we had a good game with clinically finishing,” Villas-Boas told Sky Sports.
“This is the sort of thing we are looking at as this is what we try for all our games.
“We deserved it and created chances in all our games but today we found the net easier.
“Everybody has been fantastic, we have been putting the effort in training and working hard and we knew it was would eventually happen for us.”
