Under Mancini we were excellent but still full of mistakes and poor performances. We relied on certain players in order to perform. He was brilliant. Brought the fans together, stuck it to the rags and got us our first trophy in decades and gave us the greatest moment. Last minute winners, to steal it back from our rivals... you just couldn't write a moment like that.
Pep is just a different class though. We now perform to the same exceptional standards regardless of personnel more often than not. He's spent a fortune of course, but so did Mancini. He's just bought better generally and the board have been a lot smarter too. Let's not forget that. April on paper is a ridiculous month, what blue would have ever expected that. That shows the increase in standards again from Mancini's days.
We have the potential to seal the league in April. To win the league cup. To make it to the FA Cup final and to be in, and play the first leg of the CL semi-finals. By the end of April we could have one trophy in the bag, the title near enough secured, an FA Cup final to look forward to and one foot in the CL final. Or... we could have blown it all. But only Pep gets you to a position where you have that opportunity for unprecedented success.
