MILAN - Frustrated coach Jose Mourinho refused to offer excuses after an unimaginative Inter Milan began the defence of their Serie A title with a 1-1 home draw with promoted Bari on Sunday. Striker Samuel Eto'o netted a penalty on his league debut but a defence including new signing Lucio was badly exposed by Vitali Kutuzov's equaliser after Mourinho had switched to a 4-2-4 formation. Inter lacked a playmaker last season even with Zlatan Ibrahimovic's often inspirational displays and now the Sweden striker has gone to Barcelona, the need for a creative influence is even more starck. "After a draw at home you shouldn't look at who is not there. We had enough quality to win this match. We have not done it because we haven't played well," a red-eyed Mourinho told Sky television. "I prefer to think in this way than talk today about the lack of a creative player. I expected more from my team. I don't want to justify losing two points." Inter, who signed a host of players in the close season including debutants Diego Milito and Thiago Motta from Genoa, were priced out of a deal for Chelsea playmaker Deco while Real Madrid's Wesley Sneijder is not keen to move. Inter meet AC Milan in the derby next weekend and Mourinho is keen for a creative player to arrive before the transfer window closes at the end of the month. "If one arrives then great. My feeling is that the club is doing everything possible to bring a playmaker in but if one doesn't arrive and everything possible has been done, there'll be no criticism," said Mourinho. "Tomorrow I begin my work for the derby." The Portuguese coach added that Ghana midfielder Sulley Muntari was substituted in the first half because he was suffering in the heat given his commitment to Ramadan, where Muslims fast.
