Pep Guardiola is heading back to Barcelona after his Manchester City side was paired with the Spanish giant for the group stage of the Champions League in Thursday's draw.
There's one pretty big one: teams from the same league can't be drawn against each other in the group stage.
Paris St Germain and Arsenal, who are attempting to reach the round of 16 for the 17th time in a row, are the favourites in Group A against Basel and rank Bulgarian outsiders Ludogorets although the Swiss have caused upsets in the past.
Obviously the toughest matchup for Borussia Dortmund is Real Madrid, but this goes both ways, as it will also be Los Blancos' most hard game.
The draw was an exciting occasion for Leicester following their remarkable triumph last season.
"It's obviously a hard group, it always is in the Champions League".
That may leave Pep Guardiola's Man City to prop up the English challenge, with the team that reached last season's Champions League semi-finals likely to offer the best hope for England to boost their coefficient tally.
A total of 32 teams will be in the group stages of the Champions League and all of them will be watching with great interest to see who they draw.
It will not be paid until next summer but it dwarves the solidarity payments of around £40,000 handed to Premiership clubs over the last two seasons in European competition when our sides have underperformed.
The Foxes' last involvement in European football saw them knocked out in the first round of the Uefa Cup by Red Star Belgrade in 2000.
The Lilywhites will be playing all their home games in the competition at Wembley due to the reduced capacity at White Hart Lane, with work going on around the club's new stadium.
"We're looking forward to it".
"I have always thought that (Barca are the best team in world) with Lionel Messi and players like that".
While Leverkusen are more experienced in the Champions League than Spurs, Pochettino's side have more matchwinners and in a game where both teams are nullifying the others' press, one moment of quality could prove decisive.
BVB might have a chance to grab a point or three against Real Madrid at the Westfalenstadion if everything falls into place for the Ruhr Side.
What does the draw decide besides who's in which groups?
City were knocked out in the semi-finals a year ago - their best performance in five attempts - by eventual winners Real Madrid.
The Spurs' north London rival Arsenal makes the short trip to Paris Saint-Germain in the standout match of a Group A lineup also including Basel and Ludogorets.
Group C: Barcelona, Manchester City, Borussia Monchengladbach, Celtic.
Tottenham, which finished third in England last season, faces CSKA Moscow, Bayer Leverkusen and Monaco in Group E.
Borussia Dortmund have been drawn against Real Madrid, Sporting Lisbon and Legia Warsaw in the Champions League.
