Arsenal will need to undertake major
rebuilding in the summer even if Arsene
Wenger stays, with up to nine players,
including Alex Oxlade-Chamberlain and Jack
Wilshere, likely to move.
As the club plan for next season, there is a
sense among some players that the gap
between Arsenal and their Premier League
rivals is growing.
Those Arsenal players who go on England duty
are often regaled with stories from
Manchester City and Liverpool players about
the innovative methods used by Pep Guardiola
and Jurgen Klopp, as well as the intensity of
their training.
City players in particular are full of praise for
the facilities and the physiological and medical
back-up that they receive, which the Arsenal
players suspect is superior to theirs.
Arsenal take on City in the first of two clashes
against Guardiola’s team — they are drawn in
the FA Cup semi-finals later this month — with
Sunday’s fixture crucial to Wenger maintaining
his 20-year run in the top four.
