London, Aug. 22 : Coach Roberto Mancini has instructed his Manchester City stars to avoid making ''stupid'' mistakes that could scupper their title bid.

The FA Cup winners played some terrific stuff in this victory at Bolton but somehow failed to put Owen Coyle''s team to bed.

The Sun quoted Mancini, as saying: "We need to pay more attention. We cannot afford to concede these goals if we want to be a good team."

Last season Mancini''s men hit 60 goals and let in 33.

"We need to score 15 goals more than last year, but we cannot concede more. It is important the team has balance and that we don''t concede a stupid goal like today," he added. (ANI)
