- Chelsea loses 3-1 at Everton
- Naismith hat-trick sinks Blues
- Manchester City 11 points clear of Chelsea
- Martial scores on Man Utd debut
(CNN)Substitutes stole the English Premier League limelight Saturday as Chelsea's defense of the English Premier League title looks to be in disarray after just five games.
Jose Mourinho's men lost 3-1 to Everton in the lunchtime kickoff with Steven Naismith coming off the bench to score a stunning hat-trick at Goodison, while in the evening feature match Manchester United's record teenage signing Anthony Martial scored a brilliant individual goal on his debut as a second half replacement.
Martial, who has been compared to fellow Frenchman Thierry Henry, cut through the Liverpool defense to score the clinching goal in a 3-1 win for Louis van Gaal's team.
Naismith had struck twice in five pulsating first minutes to leave Chelsea reeling as it looked to recover from a poor start to its EPL campaign
Nemanja Matic gave Chelsea hope with a superb strike just before halftime, but after surviving prolonged visiting pressure, Everton wrapped up the three points when Naismith completed his hat-trick near the end.
The result left Chelsea with just four points, trailing leader Manchester City by 11 points, but not for the first time Mourinho was convinced his team had suffered an injustice.
'We deserved better and played for a better result,' he told the club's official website.
