Not only he has English citizenship but he represented England 30 times as in the U16-21 teams.
This is not being honest, this is just a radical opinion.
I don't think he is a shit winger at all.. In his first season at Chelsea he spent most of the time sitting on the bench while Oscar, Mata and Hazard played. Still, he managed to score 10 goals and many times he seemed like our most dangerous man. When Mourinho arrived we sent him out on loan 3 times to 3 different teams, which is just cruel(see Chalobah).. At Stoke and at West Ham he had some outstanding performances, but Premier League teams just don't build on loan players.
Of course he is not a player like Hazard, but even if a winger, he'd be a useful squad member at any English team.
