Columnist and former Chelsea player Pat Nevin is in optimistic mood ahead of tonight's game but believes everyone, from the pitch to the bench to the stands, will need to be on top form for victory.

Has anyone really got a clue whether Chelsea's glass is half full or half empty right now?

We will know soon enough I suppose, but Saturday's win at Manchester City certainly made for a more pleasant view through the bottom of my emptying wine glass that evening.

Nicolas Anelka looked thirsty for success and as such will be desperate to take part at some point tonight against his old team. Before the trip to Fenerbahçe last week, a 2-1 defeat might have been considered a decent first leg result for the Blues, that away goal usually being so important at the end of 180 minutes. It was however a disappointment following Chelsea's domination for the most of the first hour.

This tie could have been over bar the Turkish delight headlines by then, but great credit must go to the Turkish side for their fantastic fight back. Their fans will already be thinking back to the game they had against Sevilla, which ended so dramatically in a penalty shoot out win for them.

Great credit also has to go to their fans, as I suggested last week it really is among the greatest atmospheres in the world to play football and that came across loud and clear on the TV.

We tend to think of the latter stages of the Champions League these days to be the dominion of the top English, Italian and Spanish sides. It would however be such a shame if clubs like Fenerbahçe did not get there now and again because of the intensity and passion they bring.

Tonight they will hopefully witness the English version of that passion on and off the field. This is one of the half dozen games that will define the season for Chelsea and as such I expect the noise to reflect this and the support to rally the players whatever happens.

I have no doubt that there are enough good players at Chelsea to get through this one and nothing will help more, with the possible exception of an early goal, than the Bridge boiling like a blue cauldron.

I will be surprised if Chelsea fail to score in regulation time, so it will take the Turks to score themselves to edge through and that will not be easy at the Bridge.

We will see the team soon enough, but this is one occasion when it will need more than 11 players on the night, substitutions will be vital if and when the game needs changing. The talking point, yet again, will be who Avram Grant picks to start in the forward positions.

On Saturday Anelka looked as sharp as he has since joining the club, but Didier Drogba is the club's talisman, even if he had one of his quieter outings in Turkey in the first leg. Both strikers playing together could be a shout of course, but whatever the boss goes with, this decision is the one that will most likely determine the outcome of the game. Again it may not be who starts but who is on near the end of the game that counts.

Certainly all the players should be on a high after the weekend, especially as Manchester United's dropped points against Middlesbrough blew the domestic title race wide open. They are still looking over their shoulders and Chelsea just keep on getting closer, piling on the pressure.

A running theme throughout most of this season has been Chelsea's ability to just hang on in there while everyone has been talking about the other teams around us. Didn't we used to want this as we were being hammered in the media every week even when, or particularly when, the club were cruising to back-to-back league titles?

So for me the glass is definitely half full as I write and it will be totally full with something bubbly if the team can turn this one around tonight.

There was a great response to last week's quiz, and there were plenty of entries from Fener fans who had come on to the site to have a look. Every one of them contained positive and lively messages, all of which were a joy to read.

They are now officially my favourite Turkish team, and that is saying something, as I almost signed for their great rivals Galatasaray after leaving Everton late in my career.

The question as ever had a little twist which didn't fool too many of you if I am honest. It was, who are the top three teams in Istanbul and what were their positions in the Turkish league last week? So all of you who looked at the table and then suggested Sivasspor as the third side were wrong, as they are from Sivas and not Istanbul.

The correct answer was Fenerbahçe who were 1st, Galatasaray 2nd and Besiktas 4th.

This week to win another copy of the book, could you tell me which current Chelsea player was voted the Champions League's top defender in 2003-04? Answers as ever to pat.nevin@chelseafc.com and let's hope he is just as good tonight if he plays.
