Doesn't sound great does it, lots of kids can be reckless early in their career to be fair but we won't know for certain for a few years, I'd still be surprised if he's not at least lower end Prem or a top Championship player, maybe a little too early to sure he defo attracts red cards but he's defo boisterous maybe he's just inexperienced... Liam needs to learn the dark arts the Kevin Davies type tricks of roughing up a defender and getting away with it by the letter of the law, he needs to become a shithouse windup merchant and control his aggression vent it in different ways, to make them react to him he could be the best at it a total nightmare due to his physicality, he should look at people who might be similar to Sergio Ramos and think you might be the shithouse mormally but I'm here to wind you up bigtime.
Shearer was also a master at it like Kevin Davies... although he was a master at everything when it came to being an old fashioned English centre forward, even if Delap drops off in the goals department he should at minimum always be a Kevin Davies type handful if he learns those tricks.
Liam just needs to focus on learning for now and reflects on his stupid bookings, if he gets to Balotelli levels of getting stupid cards all the time into his early 20s then he could go down the same path, never fulfilling his potential but here's to hoping he keeps his head screwed on and learns from his mistakes.
