Deulofeu has been getting a lot of attention from his opponents in recent games.
The 21-year-old was an exciting member of the Toffees side during his loan spell at the club in the 2013/14 season and though he has shown his qualities during his second spell at the club so far this season, he is something of a marked man as opposition defenders are doing their best to negate any kind of threat he offers to them.
Martinez is quoted in the Liverpool Echo, saying: “I think it’s difficult. Sometimes as a player when they keep hitting you every chance they get, sometimes you are going to feel the challenge comes your way and maybe you are going to go to ground that little bit easier.
“And maybe he has to learn that but it’s difficult as a striker or an attacking player, sometimes it’s difficult to cope with the amount of bad treatment you get from defenders."
The young Spaniard is likely to learn more and more about dealing with his opponents with every game that passes. Certainly during Saturday evening's loss to Arsenal at the Emirates Stadium, he was involved in quite a tussle with Nacho Monreal throughout proceedings.
His ability, vision and technique will all serve him well but one thing that a lot of defenders do in the Premier League in order to combat the finer talents of players is to try and be physical with them, something which the Spaniard is experiencing at the moment.
Maybe that is one aspect he needs to work on in order to relish the physical battle, then his other attributes can shine just that little bit more.
