Sharethematch.com ambassador Andy Gray was talking exclusively to tribalfootball.com
BARCELONA are a better side than Chelsea, I don't think anyone can dispute that so for the Blues to go through they will need to be on even better form than they were on Wednesday.
Can they do that? I'm not so sure. They did remarkably well the other night to get the result they did, lots of things went their way - how they played defensively and some good fortune went a long way to get a result.
Even though I thought Barcelona were not quite at their very best, they still created enough chances to have won the game. And Barcelona must feel that they are good enough to win the game at the Nou Camp.
In all the games they have played at the Nou Camp this year, there has only been one game where they haven't scored more than two goals.
They can go there and yet again everything like last Wednesday can go right for them. Barcelona may hit the woodwork five times this time, Petr Cech might pull off five great saves or an offside decision may go their way.
All of these things, you feel, can still happen, but it's just a huge ask. I think I would've fancied the Chelsea of old more. The Chelsea of three or four years ago, I would have fancied to get a result there. I'm not sure this Chelsea side are as good as that.
We have to remember that Chelsea only had one shot on target pretty much during the whole of the 90 minutes when they were at home. So it's going to be very difficult for them to score.
If they do score then that gives them a great platform, but this Barcelona side is capable of scoring three - there is no mistake about that. And whether Chelsea score or not won't concern Barcelona, they still feel that they've got enough to get through.
They could've scored three at Stamford Bridge - and nobody would've complained. So I think it's a massive task.
Roberto Di Matteo does deserve a lot of credit, but I still think we need to wait. If at the end of Tuesday night he's got them through to the final then we can heap as much credit on him as we want and deservedly so. But if they get beat 5-0 or 4-0 on Tuesday night then it won't look so good.
I'm not trying to play down Chelsea's chances, I just think the lads will realise that they've got a massive job to do and everything has to go their way because without doubt Barcelona are the better side.
Back to domestic action and love him or hate him if Manchester City had have been able to call upon Carlos Tevez all year they probably would have been celebrating a first Premier League title by now.
As it is Man City have to win all their games. There is no room for error for Roberto Mancini's men now and they know that. They have got to go and win all their games - and that includes beating Man United at the Etihad Stadium and beating Newcastle away from home.
This Premier League is so competitive and unpredictable that there is room for United to drop points, of course there is. We didn't expect them to drop points against Wigan but they did. This is a strange league this year and I think it's still open and I think it's still undecided, but if City don't win all their games from now on then it doesn't matter.
When you look at Tevez it is almost impossible to say they would be top if he had played all year.
People are saying that because he's come back and got a hat-trick that they would be. It's possible because I think he is better than the others and is a perfect foil for Sergio Aguero.
I think he would've been better and I think he would've scored some goals, so would they be more than five points better off? I think they probably would be and therefore I think that means they'd probably still be top.
