On the summary about City:
4 Manchester City FC
It is testament to how far the brand has come that
commentators speak about a season where Manchester
City doesn’t win a trophy as a “failure” or a
“disappointment”. The financial reality couldn’t be more
far removed.
Manchester City’s rise has been fuelled by a rapidly
growing fan base. One report has suggested that its fan
base has grown by a staggering 523% in recent years, in
comparison, the same report also suggested that
Manchester United’s fan base fell by 19% over the same
period.
It is now the flagship brand in the group of clubs which
form the City Football Group. This international, multi-club
structure allows the City brand to be leveraged across the
globe whilst simultaneously benefiting from synergies
through association with its regional partners. As a result
City now has a diverse portfolio of partnerships ranging
from Nissan in Japan to Etisalat in the UAE.
The club’s plans to expand its stadium capacity by a
further 10,000 seats will provide a healthy boost to
match-day income in future (an area in which City lags
behind its rivals) allowing the brand to accommodate its
growing fan base whilst increasing its appeal to new
commercial partners.
That being said, the club’s performance this season will
be a cause for concern amongst some stakeholders not
least the fans. The brand’s rapid rise relies upon continual
success and many will be unhappy with the way Chelsea
seemed to win league with relative ease. City’s ageing
squad earning well-publicized large salaries must also be
considered, with many believing an overhaul is required
to revitalise the brand’s on-pitch performance.
The brand is likely to see a busy summer period with
many existing personnel on the move and this could play
a decisive role in the coming season’s performance.
There will undoubtedly be an expectation that City make
more of a title challenge next year, and perhaps more
importantly, that it makes further inroads into European
