Arsenal took a seven-point lead at the top of the Premier League after a scoreless draw with Nottingham Forest on Saturday following an exhilarating 2-0 derby victory for Manchester United that dealt a devastating blow to Manchester City's title hopes, Reuters reported. 

Arsenal could have gone nine points clear with a win at Forest, but Sean Dyche's side fought tooth and nail to secure the draw, becoming only the second team to prevent Mikel Arteta's side from scoring in the Premier League this season.

"We tried to at the end find a goal. I don't think we conceded a single shot, again. But that's the margins and we didn't find a way to win it," Arteta said, according to Reuters.
