Gary Neville has questioned the logic behind Manchester United’s decision to sell Danny Welbeck to Arsenal.

The England striker signed a five-year deal with the Gunners last week after being deemed surplus to requirements at Old Trafford following the Red Devils’ signing of Radamel Falcao.

I’m struggling to understand the logic behind the deal in two or three ways really Gary Neville

And United legend Neville criticised the Red Devils for allowing the England international to leave for a cut-price £16m, helping their top-four rivals strengthen their squad.

“I can’t work it out [why Manchester United sold Welbeck]. After all the prices I’ve seen paid this summer and, obviously I’ve been working with him the last week, I’m thinking how is it just £16million?” Neville told talkSPORT.

“There’s been right-backs and left-backs galore who have been bought for £15million this summer. How have they got him for £16million?

“I can’t work it out to this day, it’s a strange one. It really does feel strange that it’s a centre forward and actually it’s helped out a competitor, someone who will be vying for those third and four places with United this season.
