Manchester United defender Harry Maguire has sent a warning to Chelsea ahead of Sunday's Premier League clash.
Chelsea welcome second-place United to Stamford Bridge in the midst of an impressive run of form, nine games unbeaten across all competitions since the arrival of Thomas Tuchel.
The Blues are now on the edge of the top four and eyeing down the likes of Leicester City in third and Manchester United in second, but it will be one of the biggest tests of Tuchel's reign so far on Sunday.
The two teams are currently six points apart and Manchester United are themselves eight unbeaten, determined to 'spoil' Chelsea's impressive run.
"Obviously, Chelsea's going to be a tough game but we went there last year and won and we will be looking to do that again," Maguire told Sky Sports.
"They are keeping their position very nicely and build up really well and not conceding many goals, so it is a good start (for them). We are hoping to spoil that.
"It is a great reaction (to the change of manager). They are a great group of players with tons of talent and the money they spent in the summer, they are starting to gel, starting to tick, but we have got to look at ourselves, first and foremost.
"We go into the game full of confidence, full of belief. We will make sure we play to the ability of what we are capable of and go and get the three points."
With just six points separating the two sides, Chelsea will see the game as an opportunity to pull themselves towards the two and into the thick of the Champions League spots, while Manchester United will want to solidify their own spot in the top four.
