7 months ago, before Ronaldo arrived, Man United owned a Quartet of quite good strikers (in the highest form) such as Greenwood, Cavani, Rashford and Martial. When CR7 arrived, he was forced to play at the highest position in the attack.
The summer market will open from July 1 and right now, the option of bringing in another spearhead striker has been considered. According to The Athletic, Manchester United need 1 more striker, 2 midfielders, 1 defender and 1 right winger (even with Sancho). Time will tell how much M.U has achieved in each goal but the striker position is being prioritized.
Cavani will leave the team when his contract expires at the age of 35, which is not surprising. Greenwood's involvement in the legal battle is unpredictable and it is unknown when this star will return (there is information that he is in prison). In that context, Rashford is still uncertain about his future while Martial seems to be happy with Sevilla, not Manchester United.
There are shocking statistics, in the 2019-20 season, the Rashford - Greenwood - Martial trio finished with 62 goals in all competitions, surpassing Liverpool's Mane - Salah - Firmino trio (57). At that time, the "Red Devils" had an average age of 21.3. This is proof that M.U needs to reunite with a complete trio to continue expectations.
If Kane arrives at Old Trafford this summer, it could be the result of last year's meeting between Ed Woodward and Daniel Levy. The Athletic said that Woodward had told Levy about M.U's interest in Kane at the same time that Man City were eager to complete the deal. However, Man United had just signed Sancho (73 million pounds), so the budget for the 2021 transfer window was limited, everything was postponed to 2022.
Ronaldo is now at M.U and his agent - Mendes has a good relationship with Sir Alex, so it is not uncommon for him to help the "Red Devils". The Portuguese "super bo" is looking in his hometown for a striker good enough to arrange for Tottenham, paving the way for Kane to Manchester United. Benfica's Darwin Nunez is in the target area.
Mendes also has a very good relationship with Spurs' sporting director, Paratici. It was this "super-broker" who brought Doherthy and Carlos Vinicius to Tottenham before Paratici joined the North London team. Mendes is not a Tottenham or Manchester United player but knows how to help both sides.
As for Kane, he must seize the opportunity for himself at the age of 29. The England captain needs a new destination to find his first title in his career and Levy also needs to sell Kane to earn the largest amount of money possible. This is the last chance for both of them, if they hesitate, their whole careers will be ruined. Kane is currently priced at around £100 million. Last summer, he was worth £150 million but Tottenham decided not to sell him to Man City.
If Man City buy Haaland, Man United will be in trouble if they cannot find someone of enough class to face. At that time, Kane was the target of interest. The difficulty for the "Red Devils" is that they have not yet finalized a new coach, so potential contracts are still waiting.
Ronaldo will stay at M.U despite the possibility of having to play in the Europa League, but this will not affect Kane much if he comes because CR7 expires next year and his contract expires (if not activated himself).
New coaches, whether Ten Hag or Pochettino, cannot refuse a classy person like Kane. Staying in England, playing for a big team and being named is something the "Three Lions" captain should consider.
