If Pep Guardiola began the official farewells to the glorious past of his football club in Leicester on Saturday evening, then Tuesday could well bring him face to face with its future.

Just days after announcing he will leave the club at the end of the season, Sergio Aguero, the man who has done as much as any other individual to catapult Manchester City to the pinnacle of the domestic game, turned in a lacklustre display that proved one great sporting truism. Time waits for no man, not even one who has scored well over 250 goals for the club in a decade of record-breaking exploits at the Etihad.
