Well my imagination is clearly no match for yours if you're suggesting that Success has similar issues to Berahino and are comparing them seemingly only due to the fact that they happen to have the same colour of skin.
Perception is reality. Unfortunately yours seems to be rather wonky. You do understand that just because you think something it doesn't mean it's actually a correct representation of a given situation.
Well he got a bad facial injury at the end of last season and started the season just fine so that blows your psychological problems out of the water. He came on, looked a bit crap because he's barely played in the last couple of months and that's it. Like the vast majority of players he'll look better given a run in the team or at least more than 10 minutes here and there. Why you're trying to look for a deeper problem is beyond me, he was good against Arsenal and Burnley and would have got an assist had Troy not handballed it.

Option A: he's playing great when he gets on the pitch, he's training well, he's fit. Walt, and I, are idiots. He didn't bottle one on ones and an open goal tap in, because he's mentally ready. He's p*ssed off and raring to go. Option B: he's showed great raw directness in the past, but he's currently lacking fitness, doesn't have confidence, isn't tearing up training and isn't ready to make a huge impact right now. Therefore just 'chucking him on for a half' might do more harm than good. I opt for B, because I think Walt would throw him on if he could rely on him. I think he would have seen if he was ready right now to make an impact. Playing a player out of form and fitness, isn't often the smartest way to pick up points.
Will he stay fit to play for his country? http://www.watfordobserver.co.uk/sp..._squad_for_north_London_friendly/?ref=mr&lp=9
Success has come out and disputed Mazzarri's claims that he's not fit enough, saying that he could play more than 90 minutes if asked. Hmmm.... http://www.watfordobserver.co.uk/sp...ss_insists_he_is_fit_to_play_full_90_minutes/
Success doubling down on his "I'm fit" comments by repeating them in an interview with BBCSport, describing himself as "fit and very sharp". Over to you, Walter... http://www.bbc.com/sport/football/39408261?ocid=socialflow_twitter
Walter should have try courage of his convictions to come out and say 'yes, he's fit, but he's crap' and throw it back to Isaac
Got all the makings of a really frustrating player. Will walk past 3 players and then a minute later look like he's never seen a football before. He badly needs to add some football intelligence to his game but he's still very young so that will hopefully come. His pace is ridiculous, doesn't even look like he's sprinting half the time but he just eats up the ground.
We lost the ball on 89 minutes or so and he sprinted back to get position and defend. He's fit enough.
I think he's got bags of talent, but personally I'd like to see him spending a bit less time fannying around on Instagram. The endless selfie stories he sends around gives me the impression that he thinks a lot of himself. Not a good impression to give anyone. Perhaps there is some truth in what Mazzarri said.
