Barkley made his debut for England at the age of 19 and was tipped for the top, but has not featured during manager Gareth Southgate's reign, missing out on the World Cup in Russian Federation.
A run in the Chelsea side and Ross Barkley is displaying a level of confidence that certainly was not evident the last time he was part of the England set-up.
"I was proud to see the lads do really well and see how proud the country was of the boys".
Thinking back to the summer and the World Cup, of course I would've preferred to have been in Russian Federation with the lads, but sometimes you just have to accept where you're at.
Many people thought the Blues would still be finding their feet under new boss Maurizio Sarri but the former Napoli manager has taken no time to adjust to life in England. "I'm so comfortable (with) the performance we have done". Running in these transitions there is no one better.
"I had a difficult spell in my last couple of years at the club and it was hard for me to leave but I thought that it was the right decision, Chelsea are a massive club and I feel like the rewards are coming now".
Barkley is also enjoying playing with someone of the quality of Eden Hazard, a situation he very much hopes will continue. You can see how he's started the season and the World Cup that he had.
"If it is an open game at Anfield you don't even have a one-percent chance", said Guardiola.
Barkley's impressive form this season has seen him compared to England legend Paul Gascoigne, but he was quick to play down the compliments.
"Obviously they were a bit cautious ofthe way we play and I think we have earned that respect, but they still pressed and still tried to play their game".
'I feel like I'm much more ready to show what I'm capable of; to show what I have shown over the years in spells. I was confident, so I was not happy that they did not allow me.
Klopp said players need a proper break to be fresher, pointing to the case of Liverpool midfielder Jordan Henderson who played for England at the World Cup in Russian Federation.
