Our best will give us a chance -WENGER

Arsene Wenger has warned
that only Arsenal's best will
give them a chance of
beating Barcelona on
Wednesday as the two most
attractive sides in European
football resume their
Champions League rivalry.
The English giants welcome
the Spanish league leaders
to north London determined
to erase the memory of last
season's masterclass, when
Barcelona crushed Wenger's
side 6-3 on aggregate over
two legs.
Although Barcelona are
overwhelming favourites to
progress to the quarter-
finals, Wenger believes his
side have absorbed the
lessons handed out in that
defeat and are a stronger
unit 10 months on.
"When you play a team like
Barcelona you need all 11 to
be at their best," Wenger
said. "For us it is important
we play with belief.
"What we have learned from
last season is in the first
half we gave them too much
respect, we were lucky to
get away with that (in the
home leg).
"We are not favourites in
this game but I think we can
do it."
"We know from last season's
games that what is most
important is to play at our
level. Barcelona are maybe
better this season than last
season but so are we. That
will make the game even
more interesting."
Last season, Arsenal were
run ragged in a scintillating
first half display at the first
leg, eventually fighting back
from 2-0 down to snatch a
2-2 draw.
The return leg at the Nou
Camp saw Wenger's men
swept aside after a virtuoso
display from Lionel Messi,
scorer of all Barcelona's
goals in a 4-1 win.
Wenger however believes
that the presence of Robin
Van Persie -- who missed
the match last year -- and
Cesc Fabregas, who missed
the second leg, mean his
team will be a different
proposition for Wednesday's
last 16 clash.
Van Persie scored both
goals in Arsenal's win over
Wolves in the Premier
League on Saturday, and the
Dutch striker's form is a
source of optimism for
Wenger as his side prepare
for their biggest game of the
year.
"It took (Van Persie) some
time to come back into form
(this season), but now he is
at his best," said Wenger.
"We go into the game in
better shape than last year,
and Robin is part of that.
Then the team had less
confidence. We have matured
better, we can certainly
compete technically better
with them.
"We will try to play to our
strengths. We will try to
attack."
Arsenal's teenage midfield
prodigy Jack Wilshere,
another player who was not
involved in last season's tie,
hinted that the Gunners will
aggressively seek to disrupt
Barcelona's metronomic
passing game.
"We've got to change our
game a bit," said Wilshere.
"We need to get in their
faces and win the ball back,
if you like, be a bit nasty
with them. We have to press
them as a team."
Arsenal could also be
bolstered by the dramatic
return of Samir Nasri. The
French playmaker, initially
thought to be out of
contention for the game after
injuring a hamstring last
month, is available according
to Wenger.
"I would not rule it out but I
will not take a crazy gamble,"
Wenger said. "Physically he
is ready, but is there the
risk of a setback."
Barcelona meanwhile are
likely to be without central
defender Carles Puyol as
they aim to bounce back from
the disappointment of seeing
their record-breaking run of
16 straight victories in La
Liga come to an end in a 1-1
draw with Sporting Gijon at
the weekend.
Barca winger Pedro
Rodriguez agreed with
Wenger that Arsenal were a
stronger side from the one
beaten last season.
"It will be a very difficult tie,
different from last year as
maybe they are more
dangerous," Pedro said.
"They are in very good form.
They have great players,
especially up front. They
have Cesc and (Robin) Van
Persie, who is in very good
form.
"It will be a nice game, open,
and one where we hope to
get a good result
