Bacary Sagna says it is important that Arsenal maintain their momentum in Saturday's "massive" clash against Aston Villa at Emirates Stadium.

Arsène Wenger's side moved into third spot for the first time this season with Wednesday's 1-0 victory at Everton, while Tottenham drew against Stoke.

Spurs face fifth-placed Chelsea in the lunchtime kick-off on Saturday, and Sagna feels the Gunners could have the chance to extend their lead on both sides.

"The Villa game is massive," he told Arsenal Player. "Tottenham are just one point behind us, but we were 12 points behind them in February. We are here now and we deserve to be here, but we have to give even more.

"We can't think about 'what if?' - we just have to give our best and look after our team, not [concentrate] on the others.

"Villa have very good players, like Charles N'Zogbia and Gabriel Agbonlahor. We know they can bring us problems. But we must focus on ourselves and make sure we play."

Alex McLeish's side have been struggling for form, but Sagna expects a major challenge from the Midlanders tomorrow.

"There are no easy games," he said. "Even if everyone thought we would win at Everton, we were struggling. It was a hard game physically and mentally as well because it is never easy to win away.

"We can't anticipate the games. When Villa came to us in the FA Cup they were 2-0 up, so it is a warning. We know they have good players, and can play good football. But we are at home and we need to impose ourselves."
