I think it may be worth a little dabble on the 1X for this first leg. Barcelona don't have the best of records in this competition - they won it last year against Betis, but prior to that they hadn't won it since 1996, losing the following three finals (97-99) to Real Madrid, Mallorca and Valencia.
Barça are just back from a gruelling pre-season tour of the USA and Mexico, having travelled nearly 26000 kilometres in total, and it seems many of the players have been complaining that they're exhausted, with Eto'o having commented that even with the sleeping pills they've been given, he's only been getting 4 hours sleep a night. Their pre-season results so far have been a 3-0 win over Aarhus, a 3-0 win against Tigres, 1-1 with Chivas, a 4-4 with América (where Barça had to score 3 times in the last 5 minutes to come from 4-1 down), and a 4-1 win over New York Red Bulls.
Espanyol pre-season have beaten Peralada 5-0, lost 1-0 away to Villarreal, drawn 2-2 with AE Larisa 1964, beaten Ergotelis 3-0 and drawn 0-0 with Palermo.
Spain are playing Iceland tonight in a friendly, but Iceland didn't call up Gudjohnsen, while Spain released Xavi and Puyol due to them struggling with injuries (although
www.as.com seems to think they may be set to play for Barça on Thursday in spite of that). That leaves Iniesta as the only Barça player in the Spanish squad, although the game was moved to tonight specifically to allow any Barça/Espanyol players involved to play in both the Spain game and the Supercopa game, so Iniesta may be involved. Edmilson will also be away on international duty. Barça will certainly be hoping that Puyol is available for them, as their defence has looked shaky without him (he missed the last two games of their tour, where they conceded 5 goals).
For Barça, this will be the first of 6 games in the next 19 days, along with the return leg on Sunday, the European Supercup against Sevilla, a friendly against Bayern Munich, the final of the Catalunya Cup against Espanyol, and the opening match of the league season against Celta. With a schedule like that in store, I think Barcelona will be happy enough with a draw here and look to settle the tie in the home leg on Sunday.
The one slight worry though is the fact that Barcelona have won their last 4 games away to Espanyol, and 6 of the last 9.
Will wait until the team news is a bit more concrete, but in particular if Puyol is missing, I may go for the 1X. Overs may also be worth considering.
