Europe's premier club competition gets underway this week, with a number of potential future superstars set to play key roles

With Bayern failing to sign any top-class replacements for Arjen Robben and Franck Ribery over the summer, the weight of responsibility has grown substantially on Canadian international Davies.
While Kingsley Coman and Serge Gnabry remain Niko Kovac's first choice wide pair at the Allianz Arena, Davies is seen as the first reserve – along with Ivan Perisic – and has all the tools to make it at the very highest level.

Ajax may have sold a number of their young stars following last season's run to the Champions League semi-finals, but that has allowed a new batch of teenage stars to break through in Amsterdam.
The most impressive of them so far this season has been right-back Dest, whose performances have been rewarded with a first cap for the senior United States side as well as a fresh contract with the Eredivisie champions.

Few 16-year-olds get the chance to play for Barcelona's first team, and even fewer make the impact that Fati has during the opening week of the season.
In just his second appearance for the Blaugrana he found the net against Osasuna before marking his first start against Valencia with a goal and an assist inside seven minutes at Camp Nou.
It remains to be seen how many chances he gets once the likes of Lionel Messi, Luis Suarez and Ousmane Dembele return to full fitness, but he has certainly made his mark on Ernesto Valverde.

The son of former Leeds United defender Alf-Inge Haaland, the teenage striker has been in superb form for Salzburg in his first full season with the Austrian champions.
Having scored nine times in a game for Norway during the Under-20 World Cup over the summer, he has backed that up with 14 goals in eight games to kick-off the new campaign. He has now earned a first full international cap, and is already being linked to a host of top European clubs.
