Alexis Sanchez is definitely good enough for City and for most clubs. He doesn't suit the Barcelona system perfectly but even then hasn't done a bad job there, scoring 1 goal every 2 games last season. Considering we went balls out to sign him just over a year ago, if he's being sold for £18million then I could see us being interested. Personally I would prefer Isco but anyone with some pace, skill, and quality would be a welcome addition to our too slow and methodical squad.
