Martinez reveals Everton working with Barcelona over Deulofeu recovery
The 19-year-old will travel to Spain later this week and Martinez told evertonfc.com: "We're working with the two medical departments - of our Club and of Barcelona.
"They're working together because, as you can imagine, there are many things to take into consideration and it's important they have a look as well. From there, we're going to use the best possible route to treat the player.
"Gerard has got a good feeling about him and all he wants is to get back as quick as he can. I think this is going to refresh him and it's going to make him a real impact player when he comes back, so we're excited about that."
