LONDON (Reuters) - Manchester City manager Pep Guardiola is planning to rotate his team for Tuesday's Champions League clash with Celtic, but would not confirm if striker Sergio Aguero will get a chance to redeem himself following his red card at the weekend.

City are guaranteed second spot in Group C behind Barcelona and a place in the knockout stages irrespective of what happens in the final round of fixtures and Guardiola said he would make a late call on whether Aguero would feature.
