Ferdinand said on his YouTube channel: "We look shaky. The goalkeeper doesn't fill me with massive confidence. I've got to be honest with you, he made a great save in the game from Joshua King, when he came out with his feet, he did really well there.
"But from set pieces, even outside of the goal, he's coming for things that are 50-50 and he's not sure. The whole backline doesn't look good in that area, not just the goalkeeper to be honest with you.
"He [Bayandir] needs to liven up. I know that, definitely. I'll tell you what I'd do, I'd be getting him out on the pitch every day and smashing balls under the crossbar.
"He's got to get used to it, he's got to get used to contact and work out a way. Make sure the referee is aware by the way that there's going to be contact. Shout, get him aware to look at you so if there's any contact, like in the Fulham game, that you get the free-kick.
"I don't think he talks enough, he doesn't make people aware of what's going on and then his decision-making in those moments hasn't been good enough. I don't think he's seen enough of that, Declan Rice whipping balls right under his nose. He's not on his own by the way in lacking a bit of confidence."
