Watford striker Troy Deeney
The Magpies - who have yet to be formally linked with a move for Deeney - were previously listed as 8/1 and 6/1 outsiders for the 28-year-old, with West Bromwich Albion (now also 9/2) the front runners.
So could a switch to St James' Park be on the cards this summer?
Do Newcastle need a striker?
It certainly seems that way, with Burnley's Ashley Barnes the latest to be linked in that position. Reports claim the Magpies are ready to offload Daryl Murphy, which would leave them with only Dwight Gayle and Aleksandar Mitrovic as out and out senior centre forwards.

Is Deeney the type required?
He's the perfect fit for a one up front system, with his strength and frame helping to bring others into play. While he would also complement Gayle, with this season's top scorer preferring to stretch defences with his pace. As Watford's captain for a good few years now, Deeney's leadership skills would come as an added bonus.

What are the chances of a deal being struck?
Newcastle might not be the only club chasing Deeney, with West Ham United, Everton and West Brom also credited with an interest, and a move to the Hawthorns would have obvious appeal to the Birmingham native, who has been valued as highly as £30 million in some places. It had been suggested that Deeney didn't see eye to eye with Watford manager Walter Mazzarri, although the Italian's imminent departure may convince him to stay at Vicarage Road. That said, a club of Newcastle's stature could be hard to ignore.
