The expression of ‘fears’ and ‘prejudices’ is valid in the context of a blog but I prefer to consider the evidence and your is a little thin and perhaps outdated?
Regarding Bale, go and have a look at his utter failure to trouble Maicon in the recent City Spuds match when he failed to replicate the excellent performance v RM which seems to have been a long time ago now!

Villa offered little threat to Maicon and so it isn’t possible to judge his defensive qualities based on this single 90 minutes. However, on the Ronaldo comment I would point out that Little Ronnie has torn most full backs apart in his time and is seldom ‘off form’ so I’d certainly start Zaba and probably finish with him too. It wouldn’t surprise me to see Maicon come on to play right side of midfield for the last 20 mintes or so, but at 31 years of age and miles of hard competitive football in his legs, I doubt Mancini will be looking to play him twice in a week. He’s more likely to be another ‘Paddy Vieira’ type signing, an icon and exemplar in the dressing room and training pitches, but not a first team fixture. He’ll cover RB, RWB and RMF and make important contributions when he’s needed and IMO, in Maicon we have a real asset.
