I get why Martinelli frustrates people, but come on - the man has scored a goal, missed a sitter and missed a sitter assist within the first 23 minutes. He's rusty and probably a bit low on confidence but he's such a good player to have. He has shown exactly what he brings this past week when he doesn't get isolated out on the left touchline.
I'd love to play 4-4-2 with him and Gyökeres in the attacking phase against lesser opponents like these.
