Serge Gnabry’s superb strike on Monday night booked the Gunners’ place in the semi-finals of the competition at the expense of the highly-fancied CSKA Moscow.
“CSKA are a really good team, we saw some videos during the week and their pressing was impressive,” Bellerin told Arsenal.com. “They are a team who would never get tired, but we knew how to play them and the coaches gave us good advice.
“Now we feel like we can beat anybody, we don't care who it is. We have been defending really well recently, including in the under-21s, and every day we feel more comfortable at the back.
“We just need to keep showing the same character. We are not scared of any team because after what we have done over the past two games, we know we can do anything.”
