The FA Cup semi-final between Manchester United and Manchester City will obviously be a huge game for both clubs, but especially for City.
Given the resources and playing staff at their disposal, City are in danger of being the season's big underachievers.
I am not sure that even winning the FA Cup or the Europa League - regardless of whether they finish in the top four or not - will be enough to keep Roberto Mancini in a job.
When you look at what a poor Premier League it has been this season - in terms of United, Arsenal, Chelsea and Liverpool all performing below their best through the campaign - you have to think that City have missed an opportunity. The club's owner will be wondering if they are getting a full return on their huge investment.
Once again, despite all the millions of pounds worth of talent on show in their quarter-final against Reading, it was a poor performance settled by the odd goal which sent them into the last four. That kind of unconvincing showing has occurred this season far too many times.
The opposite happened in United's win over Arsenal the day before. Alex Ferguson's starting line-up - which featured seven players who usually earn their corn in defence - looked very poor on paper, but they mustered a match-winning performance against their main title rivals.
Arsenal may have outplayed United, but the Red Devils played to the strengths in their team selection and took the chances when they came.
Even the managers of the two sides contesting the other semi-finals - Bolton's Owen Coyle and Stoke's Tony Pulis - seem much more adept at getting the most out of the players at their disposal. It's great that one of those two sides will be in the final. Any complaints that they are 'unfashionable' clubs are unfair. They both deserve their trip to Wembley.
For all the star names and quality right through their squad, City are in the semi-finals following a very kind set of fixtures. The only Premier League side they have faced up to this point is Aston Villa, and Gerard Houllier put out a team which was as good as waving a white flag against them.
Mancini already has Carlos Tevez, Mario Balotelli and Edin Dzeko to call upon up front, but there is plenty of talk about Mancini going in for Edinson Cavani in the summer.
How many forwards does he need? He is already struggling to get the best out of Balotelli and Dzeko, while even Tevez's unerring dedication appears to be waning of late.
Mancini has not helped matters with his thinly-veiled criticisms of several of his players either.
To get the most out of a highly-paid squad full of egos, perhaps City need to find a boss with greater man-management skills.
