Celtic have one foot in the Champions League group stages after a Scott Sinclair double helped his side to a 5-0 thrashing of Astana in their play-off round first leg in Glasgow.

An own-goal from Evgeni Postnikov opened the scoring in the 32nd minute before Sinclair doubled Celtic's advantage 10 minutes later.

The English winger then grabbed his sixth goal of the season on the hour before James Forrest added another in the 79th minute.

Leigh Griffiths helped round off the rout in the 79th minute with a deflection off Igor Shitov to help the Scottish champions secure a commanding advantage to take to Kazakhstan for the return leg next Tuesday.

It is a major boost for Brendan Rodgers' side who are now within touching distance of sealing their place in the lucrative group stages for a second successive season.

"It was an outstanding team performance and the boys deserve a huge amount of credit. They managed the game very well," the Celtic manager said.

"We scored five goals and missed one or two with that. To do that at this level of competition shows great composure."

Having narrowly seen off Astana in the third qualifying round last year, Celtic knew the threat their opponents could pose and piled on the pressure from the start in search of a positive result to take to Kazakhstan.

Sinclair was first to come close as he fired wide when the ball broke to him in the box from a free-kick before Griffiths somehow sent a powerful header off-target.

After soaking up the pressure, Astana were arguably enjoying their best spell of the half when Celtic took the lead.

Australian midfielder Tom Rogic confidently took a perfectly weighted through ball from Mikel Lustig in his stride before charging down the right wing.

The Socceroo star then got the break of the ball as he cut into the box before clipping a shot over Aleksandr Mokin that was going wide before Postnikov applied the finishing touch to send it into his own net.

Stung by his mistake, Postnikov came close to making amends at the other end minutes later with a powerful downward header after connecting well with a corner.

With half-time looming, Sinclair doubled Celtic's advantage.

The winger beat the offside trap to race on to a deflected ball and burst into the box before sending a shot into the far corner from a tight angle.

Sinclair then took advantage of hesitation in the Astana defence to make it 3-0.

Romanian referee Ovidiu Hategan allowed play to continue after Rogic and Ivan Maevski's clash of heads and Sinclair played a neat one-two with Griffiths before slotting through the legs of Mokin.

Griffiths was again the architect of Celtic's fourth. The striker held the ball up after collecting a long pass before knocking into the path of the on-running Forrest, who sent a low angled shot past Mokin.

The Celtic striker looked to have got the goal his play deserved late on when he controlled a pass from substitute Stuart Armstrong, cut into the box and sent a deflected shot past the helpless 'keeper.

However, Shitov's decisive intervention ensured it was another own-goal.

"Celtic played at a high level and every time they shot there was a goal," said Astana coach Stanimir Stoilov.

"We started quite well although after several small mistakes individually we got punished and in a game of this level the results are quite dramatic."

Celtic manager Brendan Rodgers hailed his side's outstanding display as they moved to the verge of the Champions League group stages with a 5-0 thrashing of FC Astana in Glasgow.

An own goal from Evgeni Postnikov and two goals from Scott Sinclair either side of half-time had the Hoops cruising to victory before James Forrest's strike and a late Igor Shitov own goal rounded off the rout.

It means the Scottish champions will take a commanding advantage to Kazakhstan for the return leg next Tuesday and puts them within touching distance of sealing their place in the lucrative group stages for a second successive season.

"We've had a number of outstanding performances since I came in but this was a different game and a different occasion," Rodgers said.

"Every game in this qualification is a pressure game. The pleasing aspect is how the players coped with that - their calmness in possession, how we circulated the ball and how we opened up the spaces and tired Astana out.

"It had everything in it -- creativity, pressing, a real good structure to the team and good organisation.

"Some of our play was outstanding.

"We scored five goals and missed one or two with that. For a Scottish side to do that at this level of competition against a side that a couple of years ago were drawing with Atletico Madrid and Benfica and show that level of composure makes me really proud of the team.

"It was a brilliant performance. Very complete in many aspects of how we work."

It was a marked improvement from last season when the Hoops narrowly saw off the Kazakhstan champions 3-2 over two legs in their third round qualification match of the same competition.

And Rodgers, who led his side to an unbeaten domestic season as they collected a treble, praised the progress his side have made since his arrival at Celtic Park last summer.

"It was a great demonstration of the work that the players have made and how they have progressed over the course of the last season," the Celtic manager said.

"We made a big step forward last year. We had a physical courage to work but over the course of the season we played a game that you have to be able to play under pressure.

"That progress is continual and I think you see tonight the marked difference from when we won here last season 2-1.

"There is a maturity in performance, an excitement and creation of chances.

"Tactically the players are thinking about football. It's not just about going out and running about and hoping.

"We are seeing that development and it is great to see young Scottish players in particular having that composure, quality, hunger and desire to play the game to that level."
