It is the quiet ones you need to watch.

James Forrest might be the only Celtic player who doesn’t have his own song. On this form, however, the Parkhead winger is dictating the tune for Brendan Rodgers’s side.

Hitting the high notes has been an issue for Celtic this term in what has been a sluggish start to the campaign.

But against Hibs they were back on it, with Forrest orchestrating the downfall of the Leith side.

The 27-year-old did not repeat his goal-scoring heroics of McDiarmid Park but he had a role to play in each of the four goals Celtic scored against Hibs at the weekend.

Added to Forrest’s industry and craft is another intriguing aspect that came to the fore on Saturday; his synchrony with Australian midfielder Tom Rogic.

In an opening half that is as impressive as Celtic have played this season, the Rogic and Forrest combination was able to cut Neil Lennon’s side open at will, one-two exchanges here, beautifully weighted passes there and the result was that Celtic carried a menace that has eluded them following a protracted start to the campaign.

Order might not quite be restored – Celtic are breathing down the necks of Hearts rather than leading from the front – but for the first time since January, Brendan Rodgers’ side have enjoyed three successive wins.

But more than that, they look far more like the Celtic of recent seasons.

The game hadn’t hit the five-minute mark on Saturday than they had hit the woodwork twice – by the time the game drew to a close they had hit the post and the crossbar four times – and there was an immediate sense of appetite and endeavour.

It is, though, one thing to do it domestically and another to do it on the European stage.

The Europa League comes calling again on Thursday night with Celtic off to Germany to take on Leipzig, who currently sit fourth in the Bundesliga after a 0-0 draw at the weekend.

Early indications suggest a two-way fight between Celtic and Leipzig for the runners-up spot in the group and as such Rodgers will be keen to take something from the game on Thursday night, even if that just means encouragement in terms of the performance put in.

On Saturday’s evidence there is a bit of a swagger again to the Parkhead side but it will be interesting to see just how they fare if they go into the game against Liepzig without the influence of Scott Brown in the middle of the park.

The Celtic captain last just over 20 minutes of the game before having to hobble off, with the indications being that he could well struggle to get the boots back on for Thursday. Three times Brown was treated by the Celtic physios before admitting defeat and heading up the tunnel.

If there was a silver lining to be found it was in the performance of Callum McGregor who then deputised for the former Scotland captain, with his display not lost on his manager.

"He was brilliant,” said Rodgers. “There's only problem when you move Callum McGregor, you want Callum McGregor to be in the other position. He's absolutely tactically brilliant. He played three positions today.

“His brain is of a top-level performer. Tactically, he's such a special player to work and he's got this unique quality for up here in Scotland, he keeps the ball, which at the top level you have to be able to do. He keeps the speed of the game going for us.”

Odsonne Edouard netted a double after being denied by the woodwork on a couple of occasions and with Leigh Griffiths toiling to be fit for Thursday night, the Frenchman could be expected to lead the line against Liepzig.

"He's a top-class player,” enthused Rodgers. “I never had any doubt about that. He's played out of position at times, off the left side, because it doesn't work with the two of them right up there, so he's had to forfeit a little bit for the team. If you look at his stats when he plays as striker, he's a goalscorer. He's different to Leigh, and Moussa was for us, but he's a top talent. He could have had three or four goals today but the fluency when he plays up there and how he moves, our intelligent players work off that.”

Rodgers also insisted that Brown will be given every chance to prove his fitness ahead of Thursday’s game, although it would appear that it might come too soon for him.

“It looked a sore one when he was coming off, so I just have to wait and see on that,” said the Celtic manager. “You know what he's like, he's a warrior and will do everything he can to be there.

“He looked like was struggling and you what he’s like, he wants to play on. He wasn’t going to do himself or the team any favours, he was struggling to get about the pitch.

“We’ll see how he is in a couple of days.

“I don’t know if it’s the same injury.

“He thought it was maybe his calf and he then maybe his knee. We’ll just have to wait and see.”
