Manchester United manager Ruben Amorim says his side found it difficult to defend against Kamaldeen Sulemana during their win over Southampton.

The Ghanaian scared the Red Devils defence on several occasions during the Premier League meeting at Old Trafford on Thursday, January 16.

Kamaldeen completed the most dribbles in the game and almost always eased his way past Leny Yoro on the left side of Southampton's attack.

Despite Amad Diallo scoring three goals in the last 12 minutes of the game seal all three points for United, Amorim was quick to acknowledge the troubles of the Black Stars winger.

"They (Southampton) did a very good job creating spaces between the lines," Amorim said.

"Their number 20 [Kamaldeen Sulemana], with a lot of space behind him, we had some difficulties stopping that player."

Manuel Uguarte's own goal from a Tyler Dibling flick opened goal for the Saints before Amad's hat-trick.

Kamaldeen was only starting his third Premier League game of the season.
