Bayern Munich defender Joshua Kimmich has been impressed with how quickly former coach Pep Guardiola has been able to have an impact at Manchester City.
The Spanish mentor led Bayern to three consecutive Bundesliga titles before joining the Citizens in the Premier League at the start of this season.
Guardiola has made a perfect start at the Sky Blues, winning every single one of his eight games in charge in all competitions, including a 2-1 win over arch-rivals Manchester United and consecutive 4-0 wins over Gladbach in the Champions League and Bournemouth in the Premier League on Saturday.
"I've seen their games against Manchester United and Borussia Mönchengladbach, the way they're topping the table is extremely commanding," Kimmich told ESPN FC.
"It's fascinating to see the way he's been able to leave his mark on the team in such a short space of time. They play a completely different football than last season. If I'm honest I'm not surprised, however."
Kimmich believes Guardiola changed the way football is played in Germany during his time with the Bavarians and expects him to have a similar impact in England.
"In Germany, some people said he failed at Bayern because he didn't win the Champions League. But I think Bayern were rarely as dominant as under him, when they won three championships in a row," he added.
"He's somewhat revolutionised football here. And I believe his influence in England will be devastating, too."
Next up for Guardiola and City are two away trips to Swansea City, first in the League Cup on Wednesday, followed by the Premier League on Saturday, before they travel to Scotland to take on Celtic in the Champions League.
