Diego Reyes is without a club at the moment, having left Porto at the beginning of July. I know he had an injured hamstring towards the end of the season but, it would be worth having him in for a medical check.
At 25/6 years of age, he's played over 350 club games and 55 international games for Mexico, mostly all at centreback. He has played a handful of games as a DM.
Out of contract, we could get him for free.
At leftback, I'm pretty sure we'd stand a good chance of getting Ajax's Daley Sinkgraven on loan. Ajax have just picked up Daley Blind from Man U. This will mean Sinkgraven losing his first choice spot as leftback. We might even get him on a loan to buy deal.
