Depends. Going by 11 best players, or making the best possible coherent 11. If the former yes, obviously. He's at worst the 5th best player Guardiola has coached in his career(Messi, Xavi, Robben, Lewandowski. I'd probably have him 4th as of yet. Xavi and Robben international careers and CL impact put them above him). Even if you rate Iniesta more than me, that's still 6th at worst. If we're making a team, i'm not so sure. Mainly I don't see the point of him in a team with Messi
Edit: forgot Eto'o. Still doesn't change the point. Comfortably among the 10 best players Guardiola has coached
