Benitez revealed Newcastle attempted to negotiate an option to buy the player as part of his loan move, but were unable to do so, and the Spaniard's keenness to strike a deal is understandable given the winger's performances to date. The relationship between fans and players has been key this year.
With the team expected to have some exhausted legs in the camp following exertions in Thursday's Europa League trip to Russian Federation in eventually beating CSKA Moscow 6-3 on aggregate, Wenger says the physicality and commitment of Welbeck could prove useful. All things considered, though, there may be an opportunity for the hosts to cause an upset. Understandably, Arsene Wenger will want to focus most of his energy on that competition, but such a long trip will see them arrive back home worn out and with next to no time to prepare for their travels to the North East.
"You can't stop speculation about players. but he is quite happy here, " Benitez said. Despite the highly-rated Alexandre Lacazette and Pierre-Emerick Aubameyang being available to play, the 27-year-old England worldwide may be the first name on Arsene Wenger's team sheet to take on the Magpies.
In eight appearances, he has scored two goals and provided two assists, but it is his confidence on the ball and progressive approach which have made him so effective for the club. With Aubameyang around, Benitez simply can not rest easy, not that he would anyway.
Arsenal are the [2.28] favourites, with Newcastle at [3.4] and the draw at [3.7]. With Benitez at the helm and the right backing in place, there is no telling of their potential, but their first and only focus will be stretching their winning run on Sunday.
Mohamed Elneny is in contention to start after seeing his red card overturned against Southampton, while Ainsley Maitland-Niles is a doubt due to a knock. Henrikh Mkhitaryan is out for the season with a knee injury.
"Some players may be exhausted, but when you are used to playing two games a week - especially at this level - I don't think it is a big advantage for us".
