I would see 4th and the FA Cup as a definite improvement, seeing as we haven't won a trophy in 9 years. Only one of Chelsea, Liverpool and Man City are going to win the league, hence if they don't win it, for example Man City could end up with just the League Cup this season, Liverpool with nothing, Chelsea with nothing.
Unless of course, Chelsea win the Champions League and Liverpool win the league. But, as long as this doesn't happen; this season, we would have won more silverware than our rivals, many of which who are having relatively successful seasons .
