Arsene Wenger’s decision to make big changes to the Arsenal side that faced Dinamo Zagreb in the club’s opening Champions League clash this season backfired, but it would appear he’s willing to take another risk. According to reports, the Frenchman is due to rest Petr Cech in favour of number two David Ospina when the Gunners meet Olympiacos in a must-win clash this week. After the loss to Zagreb, Arsenal head into tonight’s game at the Emirates Stadium knowing a defeat would severely hamper their chances of qualifying for the next round. Meanwhile, there’s no chance of Hector Bellerin easily conceding his position as Wenger’s starting right-back to the more experienced Mathieu Debuchy, according to Mikel Arteta. The Spaniard said Bellerin ‘doesn’t care’ that Debuchy is a France international - that’s fighting talk if ever it existed.
