Johnson still a Spurs player despite Palace interest, says Frank
Several British media outlets, including the BBC and Sky Sports, reported that the Eagles have had a £35 million ($47 million) bid for the 24-year-old accepted but that Johnson is yet to green light the move.
The former Nottingham Forest winger is also attracting interest from Bournemouth, who look set to lose their top scorer Antoine Semenyo to Manchester City in the early days of the January transfer window.
"Brennan has been a top professional," said Frank at his pre-match press conference on Tuesday.
