I'm trying really hard not to bite...but you did me with that last line.
"Overreact like someone got murdered" - right, I mean...an honest assessment of a player's inept performance is very similar to how I'd behave had I witnessed a murder, clearly.
Saying he played well - I strongly disagree. You seem to be satisfied that running forward regularly makes a good performance. I'm not knocking the lad's stamina, just his footballing ability. He was exposed because he is a poor player, plain and simple. When Puncheon isolates him one-on-one, that is not the team performing badly and defending poorly as you implied, that is Lambert's lack of tactical nous putting a slow, inexperienced full back against a winger like that. And Puncheon is hardly Cristiano Ronaldo is he!
If Stevens comes up against Hazard, Silva, Valencia, Walcott or Bale I think he might end up with his legs around his neck and his head buried deep inside his rectum.
Glad you're satisfied with his performance though.
