Final Score: Southampton 0 Chelsea 3

MANAGER Jose Mourinho has told Juan Mata and Michael Essien his door is open if they want to leave Chelsea.

Mata reacted furiously to being substituted in Chelsea’s 3-0 win over Southampton.

The Chelsea forward did not shake Mourinho’s hand after being withdrawn in the 53rd minute and he flung his arms up in the direction of the touchline, where the Blues boss was standing.

The 25-year-old, who has started just nine Barclays Premier League games this season, had to be calmed down by Michael Essien, who was on the bench at the time.

Mourinho claims Mata reacted that way because he was unhappy at the scoreline, which stood at 0-0 when the former Valencia man was substituted.

Mourinho does not want to lose Mata in the transfer window, but he admits he would be happy to talk to the player if he is unhappy.

‘‘I don’t want him to go.

That is my opinion, my wish, but my door is open,’’ the Chelsea manager said.

‘‘The club’s door is open too so when a player wants to speak to us we are there waiting for them.”

Essien’s future at Chelsea was thrown into doubt when his agent suggested that he could leave the club due to a lack of playing time.

Mourinho, again, stressed he wanted to keep the player, but admitted that he could not guarantee first-team football.

‘‘I offer nobody – not Michael, not nobody – guaranteed playing time,’’ he said.

‘‘I understand that players think about national teams, the World Cup and playing regularly, but my players have to think of the team before the players. Michael knows that perfectly.’’ Mourinho’s decision to replace Mata and Andre Schurrle with Willian and Oscar turned out to be a wise one.

Oscar’s deflected shot rebounded off a post into the path of Fernando Torres, who put Chelsea ahead.

Willian doubled the lead 11 minutes later and Oscar wrapped up the win eight minutes from time.

Southampton had held their own for the majority of the first half, but Oscar’s trickery proved too much for the south-coast side, who have now won once in their past nine matches.

Oscar did blot his copybook when he dived in an attempt to win a penalty following the slightest of touches from Southampton goalkeeper Kelvin Davis.

Mourinho admitted Oscar deserved his caution, but insisted the Brazilian was not a serial diver.
