MILAN, Aug 26 (Reuters) - Inter Milan coach Roberto Mancini said matches should not be played in the heat of the afternoon after his exhausted side drew 1-1 with Udinese in their Serie A opener on Sunday. The defending champions scored early through Dejan Stankovic but lost their verve as the game went on and were forced to defend for most of the second half after goalkeeper Julio Cesar was dismissed for hand-ball. Defender Ivan Cordoba scored an own goal in injury time to undo the home side's hard work. 'I have always said it. Matches in August and September should be played at least at 1800. In January we play at 2030 and in August at 1500, in 40 degrees,' Mancini said. 'In the first half we played well, we had chances to close out the match and we did not do it.' Juventus kicked off in the late evening on Saturday when they won 5-1 against Livorno on their Serie A return. Last season's runners-up AS Roma play at Palermo later on Sunday.
