Ross County 0 Celtic 2: Celtic boss Neil Lennon praised his team's attitude as they beat Ross County 2-0 in Dingwall to progress to the fourth round of the Scottish Communities League Cup.
Celtic made an early breakthrough when striker Gary Hooper poked Joe Ledley's headed knock-down into the County net in the 13th minute.
County's Scott Boyd scored an own goal and doubled the visitors' lead when he turned Anthony Stokes' ball in six-yard box into his own net five minutes after the break.
The result meant the Division One club were unable to repeat their shock upset from April 2010, when they eliminated Celtic from the semi-final of the Scottish Cup.
“It wasn't easy, it never is coming to a first division ground. The conditions were difficult to play in but I'm very pleased, it was very professional.
“The attitude and the manner we approached the game is what I wanted and the way we got the goal and the football we played at times in the final third was very good.
“I'm also very happy with the clean sheet, I think that was important and there were some very big individual performances.”
Celtic striker Hooper, who gave his side the early advantage, admitted the Division one opponents provided a stern test in the heavy rain.
He said: “In the conditions it was quite hard. It's a hard place to come and I think we did well all over the pitch.
“It was very difficult as they were in your face but we got a good early goal and we started to keep the ball well.”
Ross County manager Derek Adams had no complaints after his side were outclassed by the Clydesdale Bank Premier League club.
He said: “We kept them in it. Second half, no complaints, I thought Celtic thoroughly deserved to win the match.
“We'd have hoped to have caused them a few more problems but we didn't do that, especially in the second half we didn't get a grip of the game, we went two nil down and there was only one winner after that.”
