ROME (Reuters) - AS Roma coach Luciano Spalletti has warned his team not to get carried away by their good start to the Serie A season ahead of their midweek clash with champions Inter Milan.

Roma are joint top of the division with Palermo on six points from two matches after beating Siena 3-1 on Sunday and host Inter on Wednesday (kickoff 18:30 GMT/7: 30 p.m. British time).

"Let's just keep our feet on the ground. You can't afford to get carried away after two games," Spalletti was quoted as saying in La Gazzetta dello Sport on Monday.

"Of course, we will do our best, and the team is more mature than it was a year ago.

"But Inter and AC Milan have a little bit extra compared to us, and I'm not talking just about their players."

Before the season started, Roma captain Francesco Totti said he didn't think the team was capable of challenging for the scudetto.

But three wins in nine days, including a 4-0 victory over Shakhtar Donetsk in the Champions League, has raised Roma fans' hopes that their team could challenge for their first Serie A title since 2001.

Wednesday's game will be a repeat of August's Italian Super Cup final at the San Siro stadium, in which Roma squandered a 3-0 lead to lose 4-3 in extra-time.

It was a result that infuriated Spalletti, who reminded his players that they could not afford to make a similar series of defensive errors.

"So far this season we lost the only match that had a title riding on it. Therefore we can't be so great as people keep telling us," he said.

"There are some aspects of our game -- as we showed in Milan -- that we still need to work on.

"And when there's an atmosphere of high expectation like this it becomes as hard to deal with the victories as with the defeats."
