Hopefully, the board also support them on the transfer window. Expecting a massive change within 3 seasons is quite a difficult task if they don't have the resources to do that.
Benjamin Sesko was one of the strikers that has been linked to Manchester United for some months now, but with Amorim taking the new job, it is possible to see Manchester United shift their interest to Gyokores who already has a relationship with this coach from Sporting and has been very ruthless this season with scoring. The new coaches target will be to help United finish at a position in this season from their current 14th position to a spot where they could still make qualification for a European competition. There is still enough time for Manchester United to fight for it.
Most of the big teams in the English league has given confidence to their new coach for 3 seasons, so I think it is nothing but a test for the coach from the management to see the ability of the new coach in coaching, so far the support of the Manchester management for the new coach cannot be doubted, So course Amorim will have support money and time to get Manchester United back into form, poor form and consistency are their main problems at the moment and if Amorim is able to adapt quickly then of course their chances of ending the season in a better position could happen.
Every coach has his own player of choice, so I think Amorim will bring Gyokeres into the Manchester United squad later on, Gyokeres performance at Sporting has been quite good so far and shows great sharpness as a striker, so I think his arrival later on can be a very good addition for their squad, also the factor of his relationship with Amorim can also be an important factor in his move and also his adaptation in Manchester later on.
