Speaking on Rio Reacts, Ferdinand said: "I don't think it's about ability with Arsenal at this stage. I think it's about mindset. I think it's about mentality in this game. It's about belief. It's about going into that game and saying 'we are meant to be here. We are going to get ourselves to that final and we're going to show a way of playing that might not be what we're used to seeing with Arsenal, but it's going to be hard'.
"It's going to be ugly. It's going to be gritty. And they're going to find a way. In Saka they have a match winner who can turn a game on its head on a sixpence.
"My biggest concern for Arsenal is that without a centre forward, this Paris Saint-Germain team can go man-to-man, one-v-one at the back and be comfortable, fairly comfortable, which means they have numbers further up the pitch to outnumber this Arsenal team and and really suffocate them and keep them back."
