Newcastle United striker Demba Ba is unimpressed by the claims from West Ham United co-owner David Sullivan.

Sullivan stated last week that Ba can quit Newcastle if a rival bids £7m - with the player pocketing half the fee - and also raised the player's old, but no longer troublesome, knee injury.

"Last week David Sullivan was talking about my injury. Maybe he was sad I left Upton Park. I used to like him," Ba told the Mirror.

"With the offer he put on the table, he wouldn't have made it if he thought I had a bad knee and was injured! The way he is acting and talking now, it's bad.

"I don't know how people talk about the clause. Only me and my agent know. I don't know why people are talking about my future.

"It annoys me. It has been ­speculated about a lot. I was in Africa with Senegal and my room-mate looked on the internet and said, 'Look, you are leaving Newcastle!' I started laughing.

"I just said, 'They will see when I go back to Newcastle that they were wrong'."
