Kevin de Bruyne's hamstring problem is "not a big injury," Manchester City manager Pep Guardiola told reporters in Glasgow ahead of their Champions League tie against Celtic (Live on RTÉ2, 7.45pm).
De Bruyne limped off in the 3-1 Premier League win at Swansea City on Saturday but could be back for the Champions League Group C clash with Barcelona at the Nou Camp on October 19.
The Belgium international has been in inspirational form this season, scoring two goals and adding four assists to help City win six successive league games under Guardiola.
"We sat off Barcelona and admired them more than anything, letting them play and show what good players can do to you if you sit off them" - Scott Brown
"Kevin is not a big injury... in two and a half or three weeks, maybe he will be ready," Guardiola said.
Guardiola also expects centre back Vincent Kompany, who sustained a groin injury earlier this month, to return in two to three weeks, shortly after next month's international break.
Meanwhile, skipper Scott Brown wants Celtic to replace admiration with assertion when they take on City at Parkhead.
Brendan Rodgers' side were hammered 7-0 in their Group C opener against Barcelona earlier in the month and come up against a high-flying Sky Blues side who have won their first 10 games of the season.
Northern Irishman Rodgers claimed his side were too passive in the Nou Camp and Brown knows it has to be different against the Premier League leaders.
The 31-year-old midfielder said: "It's about getting touch tight. We sat off Barcelona and admired them more than anything, letting them play and show what good players can do to you if you sit off them.
"We need to get touch tight, get our bodies in and try to win the battles all over the park.
"We're going to have to work as a team. We're going to have defend a lot better than the last Champions League game, we're going to have to composed on the ball and take our chances if we get them.
"Watching them this season, City have changed their style of play.
"Guardiola has come in and brought a different style for them which seems to be working in the Premier League so far.
"We've got a gaffer who's tried a different style for us and it's been working in the Premiership.
"It will be a good proper game of football, both teams like to get the ball down and play it.
"It's always going to be hard playing against good players, but we need to show our qualities and step the game up a little bit."
Craig Gordon will return to the starting line-up for the Bhoys as Dorus de Vries has not recovered from a chest injury in time for the match.
