Celtic took little time to get themselves back to the top of the Scottish Premiership table.
Brendan Rodgers suggested to Celtic's official website that it was disappointing that his side were only one goal up at half-time during their emphatic win over Hearts at Parkhead.
The Hoops have taken little time to get themselves back to the summit of the Scottish game, beating managerless Hearts 4-1 on the opening day.
However, the away side were in the game for a long-time - scoreline-wise anyway - as Leigh Griffiths' opener just before the half-hour mark was not added to until Scott Sinclair doubled the side's lead six minutes after the break.
Subsequent goals from Griffiths and Callum McGregor meant that Esmael's late goal was nothing more than a consolation. And after the game, Rodgers hinted that not killing the game off sooner was something that he was not entirely happy about.
“It was disappointing that we were only 1-0 up at half-time but in the second half, they started to tire a little bit and we got in between them a bit more. We scored four but we could have had a few more,” he told the club's official website.
Having continued their domestic unbeaten run into the new campaign, it should arguably please the Bhoys supporters that Rodgers is not allowing an ounce of complacency to creep into the side's game.
The Northern Irishman is refusing to get carried away despite the emphatic win, and, over the course of the season, that should boost the team's chances of replicating their achievements from last year.
