In terms of numbers it is. Realistically probably not. Barcelona are probably going to need to beat us 5-1 or 6-2. We've conceded 2 goals so far in 9 games. Before the return leg with PSG the French team had conceded 7 in 7 games.
Barcelona at home always believe they have a chance of smashing any team. They do I suppose, but there is a naivety in what Luis Enrique is saying because we are treated just like any team. It's not impossible we could lose by a big scoreline but it's still pretty marginal all things considered. Personally I wouldn't be massively surprised if the game ends up with a lot of goals, but I fancy us to score 1 or 2 because we'll definitely get chances. There's no reason for us to be as tactically clueless as PSG were.
