Neil Lennon praised his players after Celtic bounced back from midweek European defeat with a 4-1 Scottish Premiership win over Ross County.
Dutch defender Virgil van Dijk led the charge against County with his first two goals for the club, both headers.
"It was a great reaction to Wednesday night and we have preserved our unbeaten league record which delights me," said Lennon
"We played very well. There were some good individual performances."
With van Dijk's two headed goals in either half, Celtic established a commanding lead, but County substitute Ivan Sproule reduced the deficit in the 67th minute, after replacing Marc Klok.
However, midfielder Joe Ledley, one of five changes for the visitors, returned to top form with a brace of headers in the space of five minutes and County never looked likely to recover.
"It is a constant source of frustration that we don't score enough headers from set-pieces," said Lennon.
"You are waiting on one and we get four in one day so it has been a good day all-round and puts pressure on the rest of the teams to keep with us."
The Northern Irishman had special praise for his two scorers, and pointed to more to come from the big Dutchman who stamped his authority all over the game with his aerial dominance.
"He [Virgil van Dijk] has got that in his game," said Lennon.
"He's been a bit off in his timing so we have worked with him on that and we are delighted that he has been able to come up with two.
"He is a special player, he is playing exceptionally well at the minute, as are a number of them.
"Joe has had a relatively stop-start beginning to the season. He has had a few injury problems and he is just starting to look more like himself."
Lennon also said James Forrest is a "major doubt" for Scotland's friendly against the USA on Friday.
Forrest was substituted during the second half of the match in Dingwall, though it was not immediately clear what the nature of his injury was.
