LONDON. Manchester United manager David Moyes warned that his side still had progress to make after they breathed life into their Premier League title defence by defeating leaders Arsenal.Moyes has seen his team beaten by Liverpool, Manchester City and West Bromwich Albion since the start of the season, but Sunday’s 1-0 win at Old Trafford took United to within five points of top spot.Defeats for City and Tottenham Hotspur this weekend, coupled with Chelsea’s draw against West Brom, have helped United place themselves squarely among the title contenders, but Moyes says there remains work to be done."I think it’s another step in the right direction for us,” he said. "But we’ve got a lot of big steps to take here. It’s going to take a while for me to get it all the way I’d like it to be.”He added: "We know we’ll get a few bloody noses along the way. I think the Premier League has shown that it’s not just Manchester United who are getting a few of them.”Going into the international break, just six points separate Arsenal and eighth-placed City, and Moyes says the campaign is living up to expectations following a close season of widespread upheaval."At the start of the season, we all said (this would happen) because of the changes in managers’ jobs,” he said."More likely, the reason Arsenal have started the season so well is because they’ve had continuity. They’ve had a manager who’s been there for a lengthy period.”Former Arsenal striker Robin van Persie scored the game’s only goal, heading in a 27th-minute corner from strike partner Wayne Rooney, and Moyes praised both players.  "Great players score great goals in big games,” said the Scot.Wenger attributed his side’s defeat – their first in the league since the season’s opening day – to a "nervous” first-half display and the "mistake” of allowing United to score from a set-piece.Arsenal do not play again until November 23 and Wenger, whose side lead Liverpool by two points, said the international fixture window had fallen at an inconvenient time."The international break is not welcome because when you lose a game like that, you want to play straight away again,” he said.
