Manchester United head to Stamford Bridge on Saturday knowing that they face their biggest test of the season in West London. Luckily for fans of the Red Devils, their side could hardly be in any better form.
Having beaten the likes of Manchester City, Liverpool and Tottenham in recent weeks, there is really only two sides that Louis van Gaal can challenge in order to take it to the next level to test how well his team are performing.
United have now won six games in a row, making them second to only Arsenal in the form stakes. The Gunners are currently cruising on an eight-match run, and are set to visit Old Trafford in the middle of May in what is sure to be a huge test for both sides.
But Chelsea are the team to beat, quite literally, because they haven't lost in the league since the first day of the year, in the astonishing 5-3 loss to Spurs.
Since then, and even the most ardent Blues man would admit this, Chelsea have scraped and scrapped their way through more than a handful of games to keep from losing, and more importantly, keep a healthy gap between themselves at the top of the league and whoever is chasing them.
This wasn't more evident than in Sunday's game at rivals QPR, when Chelsea had just one shot on target in the entire game, but managed to win the game with it. Jose Mourinho's teams are famously able to navigate the tougher games as well though, and considering they too have to play Arsenal, John Terry and co will know all too well that if they avoid defeat against the teams in second and third place, then they will almost certainly be champions.
So Van Gaal will take his own players, so impressive in recent weeks, and tell them to prove to him whether they are indeed capable of challenging for the title next season, and if United do manage to outgun Chelsea, they may even have a title shot in this year too.
