Rio Ferdinand could not hide his frustration when discussing Manchester United's transfer business this summer.

As always United have been linked with a whole host of players but have only got one deal across the line thus far. Donny van de Beek, who in fairness is an excellent addition, arrived for around £40million from Ajax.

But United's No.1 target, Jadon Sancho, seems no closer to joining than he did at the start of the summer.

Gabriel Magalhaes, Jack Grealish, Kalidou Koulibaly, Thiago Alcantara, Aaron Ramsey and Declan Rice are just a few of the names who were also linked with summer switches to United but for various reasons won't be joining now this summer.

Rio Ferdinand couldn't hide his frustration.

Ferdinand has compared United's transfer window to Chelsea's - and believes there's improvements to be made.

"Frank has made signing players like it’s the norm, like it’s easy – water off a duck’s back," Ferdinand said, speaking on his Five YouTube channel.

"The difference in the way Chelsea have done their business compared to say my team Man United.

Jadon Sancho is still playing and scoring for Borussia Dortmund.

"There is no noise there’s nothing going on, all you’re seeing is bang – deal. Little bit of talk, bang - deal.

"That is what’s frustrating for me and all the Man United fans."

Ferdinand went on to express his grievances over the Sancho deal specifically.

"Sancho was talked about months ago," he added.

"Still not done, it’s so frustrating.

"I’m not saying deals are easy to be done but Chelsea are showing deals can be done if you put the money down and it’s all done in the right way."
