ROME, Sept 26 (Reuters) - Coach Roberto Mancini has urged Inter Milan to make up for their losing start to the Champions League by taking all three points off Bayern Munich at the San Siro on Wednesday.
Mancini is keen to ensure Inter do not get left behind in Group B after losing their opener against Sporting Lisbon 1-0 two weeks ago.
'The match in Lisbon was our first and we lost. Now it's fundamental to get some points to avoid having to play catch-up,' Mancini told Inter's Web site on Tuesday.
'It would have been better to have met them when we had a few more points in the standings. Tomorrow they will start with a slight advantage.'
The showdown between the champions of Italy and Germany -- their first since Bayern eliminated Inter in the 1988-89 UEFA Cup -- comes a few days after both sides went top of their domestic leagues.
Inter, who were awarded last season's Serie A title following Juventus's relegation to the second division in the match-fixing scandal, last led Serie A in February 2003.
But their celebrations were tempered by a nervy 4-3 win over Chievo Verona in which they built up a four-goal cushion only to let their concentration slip and concede three goals in the final 15 minutes.
Mancini warned his players that the margin for error against Bayern would be much smaller.
'It's really important that the team stays focused and thinks hard before it acts. We have to keep our calm.
'We must not go out on the pitch thinking that we are going to score straight away.
'The goal can wait. For us, the important thing will be to stop Bayern getting close to our area.'
Inter will start Wednesday's match without two of their best midfielders.
Argentine international Esteban Cambiasso is sidelined by injury, while France's Patrick Vieira is suspended following his sending-off against Sporting.
'The injuries and the suspensions are part of the game. Unfortunately for us, they've all happened at the same time,' said Mancini.
'The fact that we will be missing two important midfielders like Cambiasso and Vieira could have an impact.
'But whoever is out there on the pitch will be well prepared and capable of putting in a good performance.'
