Sergio Agüero is likely to be sidelined for at least two weeks – ruling him out of the Manchester derby on 25 March – due to his latest hamstring problem, Manuel Pellegrini has said.

The Manchester City striker will not know the full extent of the damage until Saturday, when he will receive the results of a scan.

The 26-goal striker failed to emerge for the second half of City's 2-1 Champions League defeat at Barcelona on Wednesday evening, after feeling the problem before the break.
