West Ham manager Slaven Bilic has brushed off speculation about his future and said: "My head is clear."
Three straight Premier League defeats have led to rumours that co-chairmen David Gold and David Sullivan were considering potential replacements for Bilic.
However, the manager -- who has another year on his contract -- said he was focusing only on securing a win at Hull on Saturday.
"Nothing has changed in the last few days," he said. "What do you want me to say? There is nothing new I can say about it.
"I just concentrate on my job. I am totally focused on the next game.
"That [the speculation] does not worry me. I am not reading it or making phone calls or whatever.
"We are in a position where we can have a good finish to the season. We have a lot of games to play and there is a lot to play for."
"After three defeats there is speculation. I have a game on Saturday."
Rafa Benitez, Jaap Stam and Roberto Mancini are among those being touted for the role should West Ham part with Bilic.
But he added: "That does not annoy me. There is something between being worried and annoyed.
"But my head is clear and I am totally motivated and focused."
Bilic has ruled Michail Antonio out of the Hull trip, but the winger could return to face Arsenal in midweek.
