Arsène Wenger did not let his side practise penalties in training on Monday.

The Arsenal manager does not want to risk any psychological scars if Tuesday’s Champions League tie against Porto goes down to the wire.

At the same stage last season, Wenger’s men squeezed past Roma via spot-kicks. At his pre-match press conference, Wenger confirmed that his side are fully prepared to go the same route this term – and that is why he omitted spot-kicks from Monday’s session.

"Anything which helps us qualify is good,” said the Frenchman. “We always practice penalties in training but not the day before a game because it can have negative influences if you miss.

"However let’s see the game in a positive way. We hope we will qualify without penalties.”
