Boro want more than double that fee and are furious following Spurs’ bid.
“It is a derisory offer,” blasted Boro chief executive Keith Lamb.
“Who on earth do Spurs think they are?
“They bleated away when Dimitar Berbatov left for Manchester United in the summer — but they sold at top dollar.
“Then they want to snatch other players for derisory offers and try to unsettle players.
“That is what has happened here. Their offer is a joke.
“Why would we sell our best players to our nearest rivals? Stewart is going nowhere.”
