I posted it previously - http://www.dailymail.co.uk/sport/football/article-2403972/Willian-completes-32m-Chelsea-Mourinho-helps-land-work-permit.html Here's another - http://www.express.co.uk/sport/football/425269/Mourinho-plans-45m-splure-on-Eto-o-and-Atsu-after-Willian-signs-on-at-Chelsea There's plenty of sites that state the same thing.
I believe any potential deal for him is still far off from being complete. I think Salah and Schurrle will be offloaded before any reinforcements come in.
