Dixon: Lack of Euro experience caught up with Arsenal

Dixon told BBC Sport: "European Champions League football is different to the Premier League and sometimes it sneaks up on you.

"I don't think it's self belief, the team is in such brilliant form, you've got loads of confidence.

"The experience thing is a big thing in Europe. Every team you play in the Premier League you know how they playbut when you go into Europe, until you actually play in the game, you feel the tempo in the game, in the body, it takes a little bit of time.

"They should've won the game last night, they were a little bit blunt at the end of the pitch, but the overall performance, that's what Mikel Arteta will be talking about. That goal (for Porto) has really livened the tie up."
