Personally I'm a little skeptical regarding Brendan Rodger's ability to A) Set the team up accurately (at times), and B) Get the team fired up enough against teams we should beat (see the no shows against Southampton and Hull).
If we don't beat Cardiff then the Spurs result won't mean much.
We have been excellent against the bottom 10 teams this season. Southampton were flying when we played them and we had an off day. Hull was the one major blemish against poor teams this season. Our record against the bottom 10 teams as it stands is played 9, won 8, lost 1, scored 25 and conceded 8.
