There were high expectations of Ibrahimovic at Old Trafford following his goal scoring records with some of the world’s largest clubs.
And although he got off to a flying start with five goals in as many games, he has hit a rough patch, scoring just once in his last ten matches.
Speaking about the big Swede, Shaw was confident Ibrahimovic will find his form again.
“He’s a world-class player and I wouldn’t say it’s a dip, I think he’s been unlucky,” he said.
“He’s had chances, but the saves that have been happening from his shots are unbelievable, especially that volley he did at the weekend, with Heats (Tom Heaton) saving that.
“Of course he’s a very confident person and his confidence is always sky-high.”
Ibrahimovic was wasteful against against Burnley and failed to convert any of his chances, despite having many golden opportunities provided to him.
Fans have grown frustrated with his performances and believe a short spell on the bench would help him return to his goal scoring ways.
