Celtic assistant manager Johan Mjallby says the champions need to address their away form following a 1-1 draw with Ross County at Victoria Park.
The Glasgow giants have now gone six away games without a win in the Scottish Premier League - their worst run in the league since going 10 games without a win away from home in the 1994-95 season.
The Parkhead side have triumphed in just eight of 18 games on the road this season.
Celtic will post the lowest-ever winning tally in the history of the SPL championship, which they will collect at home against St Johnstone this weekend, and their away form has played a major part in that.
Mjallby, who picked up three SPL titles along with two Scottish Cups and two League Cups in six years as a player at Celtic, says going six games without an away win isn't acceptable for the Glasgow giants.
"That is not a record we are proud of," Mjallby said.
"It always annoys me when we don't win. I know that I work for a club where you are always expected to win trophies and games.
"I played here for nearly six years and I have that mentality that you always have to win.
"We had hoped, obviously, to get the three points and get back to winning ways and show a bit more winning mentality.
"But I think at least we looked a bit better organised defensively in this game. Our next game is at home where we have been in very good form and we have another chance against Dundee United in our final game to get an away win."
With Celtic deciding to rest a host of first-team stars, only three players survived from the team who lost 3-1 to Motherwell last weekend.
However, the much-changed Hoops got off to a perfect start when Anthony Stokes fired them in front the fourth minute.
Europe-chasing County knew they needed something from the game if they were to catch neighbours Inverness Caledonian Thistle in third place and got back on level terms in sensational fashion in the 41st minute through a superb Iain Vigurs strike.
