Willo Flood believes Celtic need to learn to kill teams off when they are in control of matches after drawing 2-2 at Dundee United on Sunday.
The 23-year-old, who enjoyed 18 months on loan at Tannadice from Cardiff until he was snapped up by the Hoops in January, came off the bench in the second half to replace Shunsuke Nakamura.
Celtic took a 1-0 advantage into the break thanks to Scott McDonald's 16th goal of the season and looked comfortable for their lead.
But two goals in ten minutes from Francisco Sandaza turned the game on its head and the visitors had to wait until the 81st minute to secure a point thanks to Lee Naylor.
"It's important for us to kill games off, and once we do that, then the points will come," Flood insisted.
"Tannadice is one of the toughest places outside the Old Firm to go to. So it was probably a point gained, because we were 2-1 down.
"But we played really well in the first half and we were thinking we should easily go on and win this game.
Lack on concentration
"It's down to a little bit of luck, nerves, lack of concentration, a bit of everything. We just need to work hard in training and get ourselves ready for the next game."
The result leaves Gordon Strachan's men just three points ahead of Old Firm rivals Rangers but the former Manchester City youngster is not concerned with the Gers' title challenge.
"We don't really worry about them. Once we have won our games, they can win six or seven nothing, it doesn't really matter," he added.
"We just need to concentrate on ourselves and it's definitely a strong position we are in. Rangers would love to be in our shoes.
"If we could nick a few more wins and they slip up again then we can go three or four points ahead before the league splits."
