Mikel Arteta's Arsenal side will play at least 62 games this season, 63 if they reach the Champions League final

Paris St-Germain and Bayern Munich are competing in "different worlds" to Premier League teams, says Arsenal manager Mikel Arteta.

And the Spaniard believes the difference in attacking quality on show in the first two legs of the Champions League semi-finals is down to the 'freshness' of the players.

Ligue 1's leading side PSG edged out the German champions 5-4 in a thrilling tie at the Parc des Princes in Paris, while the Gunners ground out a 1-1 draw at Atletico Madrid.

Arteta says PSG and Bayern's star players were able to be fresher than the Gunners' tired attacking talent, which he believes is down to differing levels of competition they experience in their domestic leagues.
