Guardiola hails clinical hat-trick hero Aguero (Reuters)

By Chris Bertram MANCHESTER, England (Reuters) - Manchester City coach Pep Guardiola praised Sergio Aguero's natural goalscoring ability after his hat-trick on Wednesday helped defeat Borussia Moenchengladbach 4-0 in their opening Champions League Group C match at the Etihad Stadium. Aguero opened the scoring on eight minutes with a clinical finish and added a second just before the half-hour mark from the penalty spot. The Argentina striker netted his ninth goal in five games this season when he slotted past visiting keeper Yann Sommer in the 77th minute.
