talkSPORT pundit Danny Murphy insisted that Arsenal need to shape up in the Champions League after knocking Porto out.

Arsenal are through to the quarter-finals of the Champions League for the first time in 14 years but it took penalties to reach that stage.

After Leandro Trossard cancelled out Porto's first-leg lead with a first-half strike, the Gunners could not find a winner and the match eventually went to penalties.

David Raya was the hero as he saved Galeno's effort to send Mikel Arteta's men through and send the Emirates into a frenzy but not everyone was impressed.

Speaking on talkSPORT, Murphy insisted that Arsenal looked nervous in the Champions League.

"I do think the game showed imbalance," the former Liverpool star said.
