Manchester United legend Gary Neville feels Louis van Gaal's team is about to face an acid test.
United sit fourth in the table after an inconsistent start of three wins, two draws and two losses, but will be heartened by their last result - a 2-1 win over Everton at Old Trafford.
"I think it's an exciting time," Neville told United's official website.
"It's going to be an important few weeks but exciting as well. We'll find out in the next few weeks as the West Brom, Chelsea and City games are all massive ones that I'm going to be at and my thought is we'll find out exactly [the level] where the team is at this season."
