Celtic skipper Scott Brown has credited manager Brendan Rodgers with developing his game this season.
The 31-year old midfielder has produced his best form a couple of years during the opening weeks of the campaign.
Brown capped another fine display at Dens Park on Saturday when he scored the decisive goal in a 1-0 victory over Dundee in the final game before the latest international break.
Brown said: "I'm learning from the manager and his tactical discipline, rather than just running about and tackling people," he said.
"From this season to last season it has been night and day for everyone and to get a good pre-season under my belt has been the main thing.
"We're still working on our high, intensive press from start to finish but we're getting fitter as the games go on and the rest will do us the world of good."
Brown will not be part of Scotland boss Gordon Strachan's squad for the World Cup qualifier against Lithuania on Saturday, having decided to quit international football in August.
The former Scotland captain reckons his decision is another reason for his return to form.
Brown said: "Going away with Scotland and training 10 days and doing double sessions here and there, I enjoyed it and loved every single moment, especially with Gordon Strachan.
"But for my body and legs I needed to call time and now it seems to be working for me.
"Every couple of months I'm getting a couple of days off here and there and the gaffer is looking out for me as well as to make sure I'm ticking over.
"Dundee gave us a good game. It's always hard, they fought and created a couple of chances but yet again we created a couple more and I was lucky enough to get on the scoresheet.
"It was my first of the season in the league so hopefully there are a couple more this season.
"But at the end of the day it doesn't really matter to me who scores the goals, as long as we get three points on the board and get the performance."
