Yes, Garnacho isn't currently in Amorim's plans, so Manchester United wants to sell him. Unfortunately, Manchester United hasn't been successful in selling him. Just yesterday, it was reported that Garnacho was being sold to Napoli, but Napoli rejected the offer due to the high price. So, if Manchester United currently wants Nicolas Jackson, I think this is the right time for Manchester United to sell Garnacho or exchange him for Jackson. According to reports, Chelsea are reportedly very interested in Garnacho. This means Garnacho could be released to Chelsea, and Manchester United wouldn't have to spend a lot of money to buy Jackson.

However, Jackson is currently in poor form. Even at the World Cup, Jackson wasn't given much playing time by the Chelsea manager. This means it can be concluded that Jackson is currently in poor form. Therefore, if Manchester United were to sign him, there would certainly be a risk for Manchester United. Although Manchester United's goal to bring in Jackson, it's to create competition for Hojlund. Because Hojlund's performance has been declining recently, Manchester United is thinking that perhaps bringing in Jackson could further motivate Hojlund to continue developing. So, we'll have to wait and see whether Manchester United actually brings Jackson in or not.
