Celtic manager Gordon Strachan was relieved to take all three points from the game at Inverness Caledonian Thistle.
The Bhoys appeared to be coasting to victory when they eased into a 2-0 lead but Garry Wood's goal for Caley Thistle meant a nervous last 20 minutes for the Bhoys boss.
Strachan said: "They weren't easy conditions today, the wind and what have you.
"We dealt with it. We're pleased we got a win because we knew it was going to be very hard. But it wasn't an easy game to referee, or play in, or watch I imagine.
"So we're just glad to get the three points and make our way home from here to Manchester.
"Gary Caldwell has got a few stitches in his foot. There are definitely a few knocks about the place, and we've got to try to find a team who can keep the ball and be a threat at Old Trafford."
