Arsenal targeted Mykhailo Mudryk before Chelsea sealed the transfer.
The Gunners were leading the race in signing the Ukrainian winger but London rivals Chelsea hijacked the transfer in a deal worth £89m.
He impressed in his debut against Liverpool last afternoon and made sure James Milner earned a quick yellow card when Mykhailo was called onto the pitch.
Mudryk made a lively display in the second half at Anfield and seems like a great addition to the Chelsea team.
Ferdinand told BT Sport: ‘We’ve all seen the clips of him and that explosive pace. But what I liked about him today is we saw soft feet on him and a good weight of pass too.
‘He was making good decisions in the final third and was showing calmness while running at speed. Those elements make him a frightening proposition for full-backs when he gets into full flow.
‘This is only his first minutes in a month or so. Who knows what he’s going to be producing after this but it’s exciting for Chelsea fans.‘
