Under-fire West Ham boss Manuel Pellegrini has shrugged off any speculation about his future.
Pellegrini is under scrutiny following a seven-match winless streak which has seen the Hammers slip towards the relegation zone.
However, the Chilean said: “We don’t talk about that. You have to very clear what you must do, game by game.
“Football changes all the time, we are working to try to beat Chelsea and after that, we will see the result.”
Goalkeeper Roberto has taken much of the flak for West Ham’s poor run and was at fault again during Saturday’s 3-2 home defeat by Tottenham.
Regular keeper Lukasz Fabianski is still injured, but Pellegrini gave no guarantee that he will keep faith with Roberto, meaning third-choice keeper David Martin might be pressed into action.
“Of course I am concerned, but it is not just about the goalkeeper,” he added.
“Every time you decide your starting XI you have the complete week to work with them, the technical staff about positives and negative things.
“We will see, our best starting XI in all the positions will start the next game.”
