While the club's own striker Aleksandar Mitrovic impressed on loan at Fulham during the same time, grabbing 12 league goals and one assist to help the Cottagers return to the top flight, the future of the 23-year-old seems to lie away from Saint James' Park.
The Serbia international is set to lead the line for his country at the World Cup, but the Balkan side will also be relying on the services of PAOK Salonika striker Aleksandar Prijovic, as they attempt to book a spot in the round-of-16 in Group E - consisting of Costa Rica, Switzerland and Brazil.
Prijovic bagged 19 goals in 28 Greek Super League games last term, emerging as the highest goal-scorer, and he could prove to be a quality addition to Newcastle's striking department.
The 28-year-old former Northampton man is an aerial threat, a strong player capable of keeping possession and a great finisher, and could prove to be a success with the Magpies after his international teammate Mitrovic failed to live up to expectations.
Prijovic is in his prime and has acquired enough experience that could see him become a hit in the Premier League.
If he manages to outshine Mitrovic against the likes of Brazil and Switzerland in Russia, Newcastle should not hesitate to go all out for him, as he could finally be the solution to their striking shortcomings.
