West Ham United boss Manuel Pellegrini insists that he has not had any discussions regarding his future with the club's top brass.

The 66-year-old Chilean was only appointed last May but after a bright start to the Premier League season, he has come under pressure in recent weeks.

The defeat to Jose Mourinho's Tottenham at the weekend was the fifth loss in their last six top-flight games.

"You must be clear, it is game by game," said Pellegrini. "We never talk about the future."

The Hammers are now just one place above the relegation zone ahead of a trip to Stamford Bridge this Saturday.

"We need to win the next game," said Pellegrini. "Football changes a lot of things."

"So we are working to try and beat Chelsea, to try to improve, and after that we will see the result.

"I never think about the future, always about the present."

Unfortunately for Pellegrini he will still be without Jack Wilshere, Manuel Lanzizi and goalkeeper Lukasz Fabianski who might remain sidelined until after Christmas.

Roberto Jimenez, who has been deputising for the Polish netminder, was jeered by his own supporters during the Tottenham defeat last weekend.

The 33-year-old has endured a torrid time since replacing Fabianski, conceding 14 goals in 6 matches.

Pellegrini admits that the leaky defence is a worry but was keen to take the focus off the Spaniard.

"Of course I am concerned, but it is not just about the goalkeeper," Pellegrini added.

"Every time you decide your starting XI you have the complete week to work with them, and the technical staff, about positives and negative things.

"Of course it's not a comfortable position (for Roberto).

"He knows exactly about his performance, he has a career behind him, he has been a very good player in big teams so of course he cannot be happy in the moment, but it is what has happened and he must try to improve."
