Manchester United have been looking to add a centre forward in the ongoing summer transfer window, with the chiefs at Carrington trying strongly to complement Ruben Amorim with his former foe Viktor Gyokeres at M16, but with the Swede striker closing in on a move to Arsenal, the Manchester Reds might need to pivot.The Gunners initially wanted to bring in RB Leipzig centre forward Benjamin Sesko, but the hefty fee demands for his signature forced Berta and Arteta to pivot. Many also suggest that the strong desire from the Sporting Lisbon striker to cater to a move to Arsenal has been highly appreciated by many within the corridors of London Colney.But this has left United scrambling, and this is why we take a look at possible options that we can consider for that #9 role.Three Viktor Gyokeres alternatives for a possible M16 moveArsenal are closing in on Viktor Gyokeres transferIvan ToneyIs Toney’s potential return from Al-Ahli a risky move for United, considering his age and time away from top-tier football?The England international left the shores of England for a mega-wage Saudi Pro League deal, but apparently he is ready to reconsider his decision and return to the English top tier, and this is where Manchester United comes in. The former Brentford star knows the league in and out, given how he has proven to be a nightmare to deal with, and he brings a dynamism of traits, given that he has that strong link-up in him complemented by his ability to dominate aerially and given how he is quite intelligent in his presses, which has been honed under Thomas Frank.If United are to bring him, Toney would be a plug-and-play option that gives the club time to get their long-term centre forward right whilst having a high-quality player up front who delivers goals. It is likely a short-term solution.Toney has those elite instincts in the penalty box which could end up complementing the likes of Matheus Cunha and Bruno Fernandes, especially if either of the two are looking to play direct balls.If we are speaking from a tactical point of view, Toney could be ideal to play in a 3-4-3 or 3-5-2 framework where you play him in the central zones (solo or with someone). As I mentioned, his pressing will be ideal for how Amorim likes to structure from the front.But there is more: Toney’s attributes in transitional situations make him ideal in counter situations, given how he had been on the end of goals time and again for the Bees in such situations.There is a thing about wages that needs to be addressed with him, though. Given how he is on a multi-million contract at the moment, he would need to take a reasonable wage cut if he wants to play at Old Trafford.Ollie WatkinsManchester United are considering a move to sign Aston Villa striker Ollie Watkins this summer and he could be an interesting Gyokeres alternative…We saw how Unai Emery started preferring others over Watkins at the end of last season, and this shows that there is a possibility of a Villa Park exit with him as well. Another former Brentford player who has been a menace to defenders for years given his high energy, pressing intensity, and technical polish.Watkins is said to be Arsenal’s backup if the Gyokeres deal doesn’t come through, and he could now end up being the solution at M16.The Aston Villa star has always thrived in vertical movements and his excellent understanding of spacing with his man whilst being on the ball, and this is where Rasmus Hojlund has time and again suffered in United colours.Watkins is more of a modern solution if this does end up going through, given how he brings a tactical dynamic.More Manchester United News:Dominic Calvert-LewinDominic Calvert-Lewin is a summer transfer target of Manchester UnitedAnother Premier League-experienced option, but this one comes with the lowest risk given that he is available on a free transfer as he looks for opportunities beyond Everton.While he brings ample experience, he is a bit different from the aforementioned two, given how DCL is more of an orthodox centre forward who gives you that raw aerial presence. Whilst this is a good trait to have, his injury concerns and lack of playing time mean he should be more of a ‘plan B’ at M16, where Ruben Amorim turns to the Englishman in games which require that physical and aerial output, given how his profile suits a back-three setup which United can use when they need to play more directly or counter aerially dominant sides.Calvert-Lewin will not be a starter at Old Trafford to me, but if United are to keep Hojlund and compound his development, then bringing him in could be reasonable given how he is an excellent penalty box poacher.
