has called on to sanction return to the club once his loan spell at expires this summer. The darts world champion also wants to see bolster his attacking firepower further by sealing a £30million signing once the transfer window opens.
Littler has made no secret of his love for United when he's away from smashing records on the oche. He combined his two passions as he walked out for his final in Birmingham on Thursday, holding a sign that read: "Man United 3-0 Athletic Bilbao. Yanited!!!!!" Moments after the Red Devil's Europa League triumph, Littler beat Michael van Gerwen to become the first player to claim five nightly wins in the competition's current format.
United face a crucial few months ahead as Amorim enters his first summer transfer window at the helm.
The Portuguese tactician has many important decisions to make in his squad revamp, including Rashford's future beyond his time at Villa Park.
Villa are yet to confirm whether they plan to trigger their option to buy the 27-year-old for £40m, so where he will be playing his football next season remains unclear.
However, Littler wants Rashford to resolve his differences with Amorim and transition his improved form under Unai Emery back to Old Trafford.
"Rashford has spent years and years at the club, and he's obviously needed to go away to Aston Villa on loan in January," the 18-year-old told the .

"He's been scoring and assisting, and we're wondering where that form was for United. For myself, I'd like to see him back.
"I watched him score on his Europa League debut when he scored two, then Arsenal on his Premier League debut. I've just watched him for years and years.
"He's obviously getting older, but he's still got the pace, and you can see it at Villa. It worked out for his first few games under Amorim, and he scored against Ipswich. I'd love to see him back."
Amorim looks set to boost his attacking ranks with a £63m deal for Wolves forward Matheus Cunha, with transfer talks reportedly advanced.
United are also expected to pursue a natural striker to upgrade on Rasmus Hojlund, who has notched just four Premier League goals this season.
And Littler would rather the Red Devils trigger the £30m release clause in Liam Delap's Ipswich Town contract than splash the cash for Napoli's Victor Osimhen.
He added: "Do you go for one of the bigger players, like Victor Osimhen, or someone like Liam Delap, who has outscored our strikers this season?
"I don't think Delap will want to be going back down to the Championship with Ipswich after this season.
"I'd love to see him sign. I'd not like to see Hojlund and Zirkzee dropped, but if they're not performing, then Amorim might go with Delap."
