Depends, as there are two ways to look at this.
There could be more pressure on us to win yet more trophies as we have a winning squad, a superb mentality and a manager of the quality we haven't seen since King Kenny. We should be hungry for more, we should put more pressure on ourselves to win more, and as a result we may well do just that... but...
There could well be less pressure on us. We've just won a massive trophy - granted, it wasn't the exact one we wanted, but I'm just as f**king happy with that as I would have been with the PL in retrospect. But what's happening here - am I satisfied with just the one trophy now? Should we have won nothing at the end of this coming season (shudder), will I be saying "oh well, there's always next year", because I can still look back on recent the CL win?
Here's what I think - there could be less pressure, but there should be more pressure. We, as supporters, need to be hungry for more. We cannot be grateful, we cannot be lenient, we cannot rest on our laurels. If we feel there's less pressure, we pass that feeling of complacency on to the team and that does nobody any good.
Thankfully, there is now more expectation, and with expectation comes that bit more pressure.
