Alex Oxlade-Chamberlain says Arsenal have a big chance of beating Bayern Munich and qualifying for the quarter-finals of the Champions League.
The England international starred in the Gunners' 4-1 win over Everton on Saturday which secured them a place in the last four of the FA Cup.
Arsenal have to win by a two-goal margin to eliminate Pep Guardiola's side but Oxlade-Chamberlain insists the team will go into the second leg full of confidence after their victory over the Toffees.
There is a 100 per cent chance we can do it
"Last season we went there 3-1 down and everyone wrote us off but we managed to get a good 2-0 win there," said Oxlade-Chamberlain. "We'll be feeling we can take something from that and in football a lot of things can happen.
"There is a 100 per cent chance we can do it. We are a top side, they will know the job's not done and we know the job's not done."
Oxlade-Chamberlain was one of Arsenal's stand-out performers against Everton on Saturday and the 20-year-old is looking forward to a trip to Wembley in April.
"You watch FA Cup games at Wembley when you are growing up and that's where you want to be," he said. "It's the first time we've been there since I've been at Arsenal so it's definitely a big thing for us.
"But we can't get carried away, we want to be excited but approach it very professionally and be as calm and cool as we can.
"Hopefully we can get through and get to the final."
