Wayne Rooney without doubt had a very career as a player, but that's absolutely been the opposite with his managerial career and I think it's be better for him not to continue with the profession as he's failed in almost all the previous attempts.
Some brilliant and exceptional players do not go on to become good coaches, it's like that and you can't do more that yourself. Giving up is not an option in his chase and pursuit of success in his career as a manager.
At least when it comes to tactics, he's not good enough, he should work with Pep Guardiola so he could know more than he does right now. I give and use Mikel Arteta as example to my pals whenever we talk about it, he's a better manager to Wayne Rooney, Lampard and Steven Gerrard. ( About Steven Gerrard, he's also not doing well with his new job, he be demanding for players signature, I'll love to see how it ends though!! )
Mikel Arteta for Arsenal would do a good job, the club knows he doesn't have enough players to execute his plans on the pitch. The January Transfer Window should make sense. Ivan Toney must be added. I just don't like the idea of Brentford, they be increasing his fee so Arsenal would look elsewhere.
