Manchester City coach Pep Guardiola said Monday it will be "nearly impossible" to repeat their thrashing of Real Madrid last season in their Champions League quarter-final duel. City hammered record 14-time winners Madrid 5-1 on aggregate in last season's semi-finals on the way to the trophy but Guardiola said ahead of Tuesday's first-leg clash at the Santiago Bernabeu he could not expect his team to repeat the feat. "To beat Real Madrid two times in the same way is almost impossible," Guardiola told a news conference.
