We may go on a good run when the pressure is off. It's the same we always give the 2nd leg once the tie is already over in the first leg.
But we will not beat Bayern.
As for the FA cup.
Burnley v Lincoln City
Fulham v Tottenham Hotspur
Blackburn Rovers v Manchester United
Sutton United v Arsenal
Middlesbrough v Oxford United
Wolverhampton Wanderers v Chelsea
Huddersfield Town v Manchester City
Millwall v Derby County or Leicester City
unless some of the big ones go out in those games we have no chance.
