Guardiola urges City to learn Celtic lesson

Manchester City manager Pep Guardiola expressed hope his players would learn their lesson after losing their 100 percent season record in a spectacular 3-3 Champions League draw at Celtic.

Aiming to equal Tottenham Hotspur's English record of 11 straight wins at the start of a season, City had to come from behind three times to earn a point in Wednesday's Group C clash in Glasgow.

City reached the semifinals under Manuel Pellegrini last season, but not for the first time, Guardiola pointed to its current shortcomings as a sign of its callowness in continental competition.
