I think that getting Alves on a free could prove an excellent move. We need competition at RB and this would allow us to save 15+ million pounds to improve other parts of the squad and give us a little more time to find a worthy candidate to take over the position long term. I think Clyne isn't as big of an improvement on our current options to justify a 15-20 million pound fee, but I'd be ok with him coming if it were on the cheap. Porto would probably ask for a fortune for Danilo which would make it a very risky move and one i'd rather see us avoid for now.
