A little more than three months have passed since Real Madrid beat Liverpool in Paris to win their 14th Champions League title, and it's already time to start it all again.
Last season's two finalists will be looking to make it all the way to Istanbul for the final, while Eintracht Frankfurt - finalists in the old European Cup more than half a century ago - will enter the competition for the first time since it took on the Champions League name. There are also plenty of intriguing match-ups, including chances for revenge and elite players facing their former employers.
It's also a much tighter schedule thanks to the World Cup, with the entire group stage taking less than two months from start to finish. Ahead of the first group games in Tuesday and Wednesday, Mirror Football has looked at some of the players with interesting stories ahead of matchday one.
