Arsene Wenger spoke about the Arsenal and Chile star last week and suggested that he and the Arsenal medical team would take the cautious approach with Alexis Sanchez and would not just take the word of the striker that he was fit and ready to play after the hamstring strain that saw him limping off a few weeks ago against Norwich City.
But having said that, Sanchez has shown a number of times that he has an amazing power of recovery and so the news that he was back in training at the start of last week tells me that he will pass any medical tests and be ready to retake his place in the Arsenal starting line up tonight.
And that could prove to be the crucial difference as our biggest rivals for the EPL title come to town: Man City have got their own injury concerns of course, but there is a good chance that their own star striker Sergio Aguero will play, even if it is not from the start.
Assuming Sanchez starts, which I do, the only real question for the boss is who to play on the right. I is between Walcott and Campbell and because of his impressive recent form I would go for the Costa Rican, with Walcott held back to be used as a super sub.
Bellerin, Mertesacker, Koscielny, Monreal
Campbell, Ozil, Sanchez
