Neil Lennon was delighted to see his Celtic side end a productive week on a high as they edged a 1-0 victory over Hearts.
A solitary effort from Georgios Samaras at Parkhead was enough to lift the Bhoys to the top of the Scottish Premier League table.
A hard-fought win came on the back of a memorable UEFA Champions League victory over Spartak Moscow in midweek, and Lennon was quick to praise the battling qualities of his troops.
He told Sky Sports: "I'm delighted. It's a magnificent win and tops off a fantastic week for us all.
"The players have been tremendous. You could see there was a bit of fatigue kicking in second half and I totally understand that. We are delighted with the win and the clean sheet."
On Samaras, who also netted the winner against Spartak, Lennon added: "Great to see him back. He maybe got a bit lucky with the goal, but overall he played well.
"We had chances to put the game away and at 1-0 you are always a bit concerned, but Georgios is a big player for us. Gary (Hooper) looked a little bit tired but the strength of the squad is good."
Samaras has been in top form for Celtic over recent weeks, but he refuses to buy into the belief that he is playing the best football of his career.
He said: "It was important that we won the game - who scores the goals is just numbers, nothing else.
"We had to get the three points today. We have the international break now, so we have to try to stay fit for the important games to come."
