Chelsea are in serious danger of being overtaken in the race for the top four following Saturday's defeat against Arsenal at the Emirates Stadium.Arsenal and Manchester United are now just three points behind the Blues, who face trips to Manchester City, Liverpool and United in the coming months.New signings are needed in January and Maurizio Sarri might be wise to change his tactics for the bigger games.One player who really disappointed for Chelsea was summer signing Jorginho as he failed to dictate the tempo of the game in central midfield.Aaron Ramsey, who started in a free-roaming position, did a sublime job in pressing the Italian and not giving him enough time on the ball.Jorginho came under heavy scrutiny after the game for his performance, with Rio Ferdinand stating that he can't defend, can't run and often gets over-run.His display also caught the attention of Jose Mourinho, who was making an appearance as a pundit on beIN SPORTS for the clash.Mourinho was asked by host Richard Keys, "If you stop Jorginho playing, do you stop Chelsea playing?" and delivered a fine piece of analysis about why Sarri's tactics aren't working."I'm not saying that Chelsea is an easy team to play against, but it's an easy team to analyse," he replied. "You know their principles and their fundamental situations."You [make things tough] for Chelsea to build in the first phase. If you close the left side with David [Luiz] and Marcos Alonso and give the ball to the right, it's hard for them."[N'Golo] Kante is playing in a position where he's making more runs forwards than to stay in the build-up for the first phase."I think he (Kante) can play everywhere. He has the qualities to be a box-to-box [player], he's scoring more goals than ever."With Antonio Conte he was playing a more defensive position because they were playing only with two in [midfield]. But now they play with three."Sarri, the same way he was doing with Jorginho at Napoli, likes him to drop in between the centre-backs, but today Ramsey is playing in that position to try to stop him.

"I remember when I played against them (for Manchester United) and we had some stats before the game where Jorginho was in the Premier League with more touches.

"If he's the player with more touches, you have to make him the player with less touches."

Spot on. Sarri deploys Jorginho in a way that makes it easy for stronger opponents to limit the Italian's influence and it's harming Chelsea.

Chelsea fans will only hope Sarri clocks onto it the same way Mourinho has, who they completely agree with on the predicament.
