In Group B, Mauricio Pochettino’s Tottenham will be tested for a second year running. Pochettino’s side are no strangers to tough groups. They were pitted against Borussia Dortmund and Real Madrid last season and beat both of them.
But this season has presented a scenario that will put his side under more scrutiny.
As well as Barcelona, who Tottenham have never beaten, Pochettino’s side will play PSV Eindhoven and Inter Milan.

Pep Guardiola’s side will also play Valencia and Young Boys, who return to the group stages this year.
Liverpool will need to produce some of the performances that got them to the final last season if they are to make it through a hostile and demanding group stage.
In Group C, Jurgen Klopp’s team will take on PSG, Napoli and Red Star Belgrade.
Former Real Madrid midfielder Kaka and Manchester United favourite Diego Forlan conducted Thursday’s draw at the Grimaldi Forum in Monaco.
The first round of group stage fixtures will start on Tuesday, September 18.
The final will be played on June 1 at Atletico Madrid’s home, the Wanda Metropolitano in Madrid.
