You lead your club to Champions League glory, and six months later you're out on your ear.

Roberto Di Matteo was not given any sentimental treatment at all at Chelsea - but who can claim to be football's unluckiest sacking?

Gary Megson at Wednesday? Lee Clark at Huddersfield? Big Sam at Blackburn?

There are scores more. Fire away, and tell us why they were hard done by.

In tonight's other Champions League game featuring a Premier League side, Chelsea are a win away from securing a place in the last 16.

However, they must come up against a man who knows what it's like to go all the way. Roberto Di Matteo secured his place in the club's history books when he masterminded their unlikely Champions League triumph in 2012, and now he's back in management with Schalke.

Champions League games are under way already and Francesco Totti, at the age of 38 years and 59 days, has beaten his own record as the Champions League's oldest goalscorer after firing Roma into a 1-0 lead away to CSKA Moscow with a sublime free-kick.

They are still playing in Moscow but if the score stays the same then group rivals Manchester City must now beat Bayern Munich at the Etihad Stadium to stay in the tournament.

Elsewhere Porto, who have already qualified, lead 2-0 in Belarus against BATE Borisov thanks to goals by Hector Herrera and Jackson Martinez.

Manchester City make five changes from the side which beat Swansea at the weekend. Yaya Toure and Fernandinho are suspended. Bayern Munich name a strong side, with just Thomas Muller and Mario Gotze missing out from the team which played at the weekend.

City XI: Hart, Sagna, Kompany, Mangala, Clichy, Fernando, Navas, Lampard, Milner, Nasri, Aguero

Bayern XI: Neuer, Alonso, Benatia, Ribery, Lewandowski, Robben, Rafinha, Boateng, Bernat, Rode, Hojbjerg.

Injuries, suspensions, a tricky draw, a bad Uefa coefficient - there are plenty of reasons why Manchester City have found the going tough in the Champions League.

But failure to get out the group stage for a third time in four years would be hugely disappointing for a club who have invested so lavishly on players such as Yaya Toure, Sergio Aguero, David Silva and Edin Dzeko.

The maths are relatively simple this evening - a defeat and City are out. A draw will knock them out unless there is a winner in the match between CSKA Moscow and Roma. A win, and it goes to the last night in Rome...

It wasn't supposed to be this way.

Two Premier League titles in three years, an expanding stadium, an FA Cup win, a glitzy new-look training campus and some of the world's best-paid players.

Manchester City have been transformed in the last 10 years; as a club they are almost unrecognisable from the yo-yo side who spent the 1990s bouncing between English football's top two divisions - or worse.

But one major negative in a long list of immense positives has been the club's performance in the Champions League. After years of looking on enviously from across the city, the blue half have been invited at last to European football's top table only to discover that their appetite isn't what it was.

Defeat by Bayern Munich tonight, and the Champions League dream is over for another year. Where did it all go wrong?
