PSG have lost only one of their past 39 home games in European competition (W25 D13), and that was against Barcelona in April 2015 (1-3).

Since their return to the Champions League in 2012, PSG have won 17 of their 24 group games (D3 L4), and last season, they conceded only one goal in their six Champions League group games.

They haven't got Zlatan any more though...

Arsenal

Arsenal make three changes from the side that beat Southampton 2-1 on Saturday. In comes David Ospina as keeper Petr Cech drops to the bench, while Alexis Sanchez and Alex Iwobi replace Lucas Perez and Theo Walcott in attack. Olivier Giroud’s wait for a first start of the season goes on – he is on the bench.  

Arsenal XI: Ospina, Monreal, Koscielny, Mustafi, Bellerin, Coquelin, Ozil, Cazorla, Oxlade-Chamberlain, Iwobi, Sanchez.

Lightning has wiped out the tram network. No power. All trams stopped, including mine. Going to cause chaos before the game.

So, it seems that Arsene Wenger was wanted by PSG on three occasions in recent years then.

But if Wenger had gone in 2011 what would Arsenal be doing now? Who would have left? Who may have arrived?

Who would be the manager? And would the Gunners have won the title?

Would PSG or Arsenal have gone close in the Champions League?

"They beat me many times at Munich [two of the last four meetings, the other two were draws] and they are aggressive. They make the game one-on-one in the build-up and when that happens it is a fight, man to man. With the ball they are so, so intelligent."

"PSG don't seem to have a settled side. One or two have already spat their dummy out. It doesn't seem to be a happy camp at the moment so it's a good chance for Arsenal to come and get a result."

Fair to assume Pep Guardiola will expect Manchester City to win at the Etihad Stadium tonight.

Guardiola has never failed to get to the semi-final stage in seven previous Champions League campaigns, four with Barcelona and three at Bayern Munich.

His opening night record is particularly impressive, with five wins, two draws and 17 goals scored, one of which came against Manchester City in 2014.

The biggest problem against Borussia Monchengladbach tonight might be the weather.

Thunder rolling round the Etihad. Lightning has lit the air - and the pitch won't need watering.

I know it's hardly unusual to have rain in Manchester but in the last hour the city has been hit by an epic storm.

Sensational thunder and lightning which has even drawn a crowd outside our offices at MediaCity...

Sergio Aguero is set to return and Ilkay Gundogan could make his debut as City begin their Champions League campaign tonight.

Striker Aguero is one game into a three-match domestic ban and missed Saturday's win at Manchester United.

But he is fit to play despite missing Argentina's recent World Cup qualifiers with a calf problem.

Summer signing Gundogan has yet to play for City because of a dislocated knee.

The former Dortmund midfielder, 25, suffered the injury last season and has been out since May.

Eight Champions League games in total tonight, with three containing British clubs.

They are:

Barcelona v Celtic

Manchester City v Borussia Monchengladbach

Paris St-Germain v Arsenal
