CALLUM WILSON will undergo a medical today ahead of a proposed £20m move to Newcastle United that will form part of a busy week on Tyneside.

A hectic weekend of transfer activity saw the Magpies reach an agreement for the Bournemouth striker and seal a £13.5m deal for Norwich City full-back Jamal Lewis.

With Ryan Fraser set to sign as a free agent after successful talks over the weekend and Rob Holding still expected to arrive on a season-long loan from Arsenal, Newcastle could have four new players in place by the time they kick off the new Premier League season at West Ham United on Saturday.

Steve Bruce’s side completed their pre-season preparations with a 1-0 defeat to Stoke City this weekend, but events at a deserted St James’ Park were overshadowed by unfolding developments off the pitch.

In a dramatic few hours on Saturday morning, Newcastle lodged a £20m bid for Wilson with Bournemouth officials, only for Aston Villa to immediately respond with a £21m offer of their own.

Crucially, though, Wilson informed the Bournemouth hierarchy of his desire to join Newcastle ahead of Villa, and an agreement was eventually struck with Magpies managing director Lee Charnley yesterday morning.

Wilson is understood to have travelled to the North-East yesterday, and is set to undergo a medical and finalise personal terms later today.

His arrival will provide a massive boost to Bruce, who confirmed over the weekend that Dwight Gayle is set to be sidelined for at least three months after ligament surgery.

Wilson, who could be handed the number nine shirt ahead of Joelinton, is a 28-year-old England international who scored 67 goals in 187 appearances during his six years at Bournemouth.

Two seasons ago, his 14 Premier League goals made him one of the most highly-rated forwards in the country and earned him a call-up to the senior international ranks. He was not as productive as Bournemouth crashed out of the top-flight last season, managing just nine goals in all competitions, but he remains a proven Premier League performer at the peak of his career.

His capture represents a marked shift in transfer emphasis from Mike Ashley, and underlines the extent to which Bruce has been able to assert his authority when it comes to dictating transfer matters this summer. While Matt Ritchie was mentioned as a possible makeweight in a deal for Wilson, Bruce was always adamant he wanted to lodge a cash offer and hold on to the versatile Scotland international.

Wilson was desperate to remain in the Premier League in an attempt to reignite his international ambitions, and is set to be reunited with Fraser, who left Bournemouth as a free agent earlier this summer.

Fraser held talks with Newcastle officials over the weekend, and is understood to have agreed a move to St James’ Park.

A 26-year-old wide player who can fill a number of positions, Fraser joined Bournemouth in a £400,000 move from Aberdeen in 2013. He played an influential role in the Cherries’ rise to the Premier League, and successfully established himself in the top-flight with a series of eye-catching displays.

He was linked with Leeds United after rejecting the opportunity to remain with Bournemouth, but Newcastle have pushed hard for his signature and their determination has been rewarded.

The same is true of their pursuit of Lewis, who is set to undergo a medical and agree personal terms after he has represented Northern Ireland in this evening’s Nations League game with Norway.

The 22-year-old left-back was the subject of a failed £10m bid from Liverpool earlier this summer, but the Reds are not expected to rekindle their interest, paving the way for Newcastle to tie up a deal.

Bruce has considered a number of different left-back options this summer, but after deciding that last season’s loanee, Danny Rose, did not represent value for money, the Newcastle boss focused his attentions on Lewis.

Holding should also be added to Newcastle’s defensive ranks in the next few days, with the centre-half set to leave Arsenal on a season-long loan.

The Magpies’ need for reinforcements was underlined at the weekend as Sam Clucas’ header earned Stoke a 1-0 friendly win.

“It has been a very difficult couple of weeks, and we can’t deny that,” said Bruce. “However, we’ve got one or two things working behind the scenes in terms of players coming in. I think all the supporters are eager to see it happen. We’re close to one or two things, so let us hope in the next 24 or 48 hours, we can bring one or two in.”
