I didn't see the game but no doubt we weren't quite as bad as people are making out. Credit to WBA, it's probably too little too late but they're making a decent fist of it lately.
You could look at it that WBA have got their good performance out of the way and will revert to type against us. That said, the Chelsea game showed what they're capable of so they shouldn't be taken lightly. Hoping for the win but would take a draw.
Not really, it's 3 points in the bag. The days of established teams putting 6, 7, 8 goals past 'lesser' sides are more or less over (with occasional exceptions) but I suspect you're too young to realise.
