I certainly wouldn't go that far but when his own manager flat out called him out on it last week it certainly leads to him being mentally weak in that respect.
Hopefully will do him good to realise as good as he is, he's no longer a guaranteed part of the XI and won't get back in there if he's not prepared to lay it all in the line. The same as every other player.
Mentally weak is way too harsh. Have you ever had a serious muscular injury or a bad break before? When you go back to exercising again, you're paranoid about every niggle, every pain, every bit of discomfort. When you've been injured repeatedly, that's only going to be worse. You can't really blame Sturridge for not wanting to push through it and end up potentially ******* himself up. I mean, he only has to look at Torres to see what that can do to you.
