The Uruguay international used his hand to help him score in Liverpool’s 2-1 victory over Mansfield Town in the FA Cup last weekend.
It marked the latest controversy in Suárez’s Reds career since joining in January 2011, with the forward banned for eight games for racially abusing United’s Patrice Evra last season.
“I didn’t see the Mansfield game, so it’s difficult to say if it was deliberate or not,” Ferguson told the Sun.
“But I think the lad is laden with controversy. I don’t know if he enjoys it or not.”
Ferguson has always supported his own players amid controversies – and the Red Devils manager was not surprised to see Brendan Rodgers leap to Suarez’s defence.
“You’re always going to support your own player,” he added. “That’s not surprising from Brendan Rogers. I’ve done it myself.
“It’s part of your loyalty and protection of the player. I just hope we don’t suffer from some of the decisions that went Suárez’s way on Sunday.”
