The youngster burst onto the scene last season at Old Trafford and has been behind the Swede in the pecking order, resulting in him receiving less game time for Jose Mourinho’s side.
Ibrahimovic has had an excellent start to his career in the Premier League and his move was described by Jose Mourinho as a gift to Rashford.
Speaking about his impact, Shearer insists training and socialising with talented players will only help Rashford improve.
“I don’t think it will be long before he is a regular,” he said.
“It has to be absolutely brilliant for him at that football club, working, training and socialising with Zlatan Ibrahimovic and Wayne Rooney.”
Ibrahimovic’s arrival will help take the goal-scoring burden off Rashford’s shoulders while allowing him to develop each week.
The expectations were carried by Rashford and Anthony Martial last season, but now they will be able to focus on improving each week while Zlatan gets on what he does best.
Mourinho is cooking a special team at United and the combination of experienced and young players is an exciting prospect for the future.
