Manchester City striker Sergio Aguero has been ruled out of Wednesday's Champions League quarter-final clash at Liverpool.

Sky Blues manager Pep Guardiola has confirmed that the Argentine forward is still nursing the thigh strain which kept him out of last weekend's 3-1 win at Everton.

"He has stayed in Manchester, he didn't come," the Spanish coach told reporters during his pre-match press conference. "He's been injured for the last two weeks and he still isn't fit.

"We will see if he can play in the derby [against Manchester United on Saturday]."

Guardiola went on to confirm that Fabian Delph has returned to fitness and could feature against Liverpool in the first-leg contest.
