Former Bournemouth boss Eddie Howe is being linked with Newcastle United.
The Sun says Celtic are also eyeing Howe.
Bookies Paddy Power suspended betting on Howe taking over at Celtic — while Newcastle want him as their new gaffer if they decide to axe Steve Bruce.
Toon owner Mike Ashley is reluctant to get rid of Bruce before he sells the club as he does not want the extra expense - despite pressure rising with Saturday's sorry 2-0 slump at Aston Villa -
The Sports Direct supremo is even drafting in former Luton boss Graeme Jones as a coach to give his manager all the support he needs in a bid to turn things around at St James' Park.
But Ashley knows he will be forced to sack Bruce if the team's results and performances do not improve quickly.
