While
there
have
been
several
unpredictable
moves
in
the
past,
but
in
2021,
prominently
the
last
summer
transfer
window
can
be
considered
as
one
of
the
craziest
ever
transfer
windows.

With
legendary
players
leaving
their
boyhood
clubs
and
club
legends
leaving
their
strong
base
for
the
new
challenges
these
four
transfers
could
be
the
most
surprising
yet
biggest
deals
this
year:

1.
Lionel
Messi
(Barcelona
to
PSG)

Sad
and
shocking
in
equal
means,
the
Argentina
and
Barcelona
legend,
had
to
leave
his
boyhood
club
after
Barcelona
failed
to
comply
with
the
financial
fair
play
regulations.
Last
season,
the
Argentine
was
eager
to
leave
the
side
but
this
summer
he
changed
his
stance
to
stay
put
and
agree
to
a
new
deal.
However,
sadly
Barcelona
could
not
afford
him
despite
selling
a
bunch
of
players
in
the
summer.
The
seven-time
Ballon
D’or
winner
finally
signed
for
Paris
Saint
Germain.

2.
Cristiano
Ronaldo
(Juventus
to
Manchester
United)

Ronaldo
was
desperately
wanted
out
of
Juventus
this
summer
and
things
started
to
go
crazy
when
Manchester
City
at
some
point
were
the
frontrunners
to
sign
him.
However,
United
quickly
swung
into
action
and
completed
one
of
the
most
long-awaited
transfers
of
all
time,
driving
Manchester
United
fans
into
a
frenzy.

3.
Sergio
Ramos
(Real
Madrid
to
PSG)

A
Real
Madrid
through
and
through,
fans
expected
the
former
club
captain
to
retire
at
Bernabeu.
However,
the
Spanish
international
reportedly
was
unhappy
with
the
new
terms
offered
by
Madrid
and
chose
to
leave
the
club
as
a
free
agent
after
16
long
years,
breaking
the
hearts
of
Madridistas.
Though,
his
signing
for
Paris
Saint-Germain
made
it
a
historic
window
for
the
French
outfit.

4.
Hakan
Calhanoglu
(AC
Milan
to
Inter
Milan)

The
Turkish
international
was
one
of
the
star
players
of
the
Rossoneri
in
the
recent
few
years.
However,
he
decided
not
to
renew
his
closing
deal
with
the
side
and
instead
opted
for
Inter
Milan
as
a
free
agent.
The
deal
was
unexpected
because
the
switch
was
to
a
direct
rival
who
are
known
for
their
staunch
rivalry.
