Arsene Wenger once led a team of self-styled invincibles to a season without defeat, but the Frenchman has conceded that Sir Alex Ferguson's current Manchester United side could be the new "untouchables".
United sit two points clear of Liverpool with a game in hand at the Barclays Premier League summit, with Arsenal a worrying 12 points off the pace in fifth.
"We are on a very strong run at the moment and we have promised to give everything until the last day of the season but at the moment Manchester United look untouchable," confessed the Arsenal boss.
"They are 12 points ahead of us and they have a game against Fulham which they will certainly win. If they win that they are 15 points in front and that means they need to lose five games.
"Let us say they lose one against us, that still leaves four. They still need to lose four other games, which they haven't done yet this season.
"But our basic target is to get into the Champions League and therefore the championship remains a priority."
