Lukas Podolski may have left Arsenal permanently three years ago but he hasn't forgotten the intense rivalry with Tottenham Hotspur.
With his former club as well as Chelsea playing in the Europa League this season, the only London representative in the Champions League this term are the Liliywhites.
Much to the delight of Gunners supporters, it's been a disastrous start to the competition for Mauricio Pochettino's side.
They led 1-0 against Inter Milan in their Group B opener a fortnight ago only to concede twice in the final five minutes at the San Siro and ended up losing the game 2-1.

That left them with a huge mountain to climb when La Liga giants Barcelona came to Wembley on Tuesday night, but Spurs found themselves 2-0 down at half-time with former Liverpool star Philippe Coutinho and Ivan Rakitic both on the scoresheet.

The Argentine followed up his hat-trick against PSV Eindhoven on matchday one with a brace against the north London outfit, taking his tally in Europe's elite club competition to five goals in two games.
