I think it's so SO obvious that Rondon's lack of confidence and goals is not his fault. Watching that compilation shows that he needs the ball to played to him early and incisively. Oh and into his feet rather than constantly aimed towards his chest/head.
The problem with us at the moment, and it was abundantly clear versus Villa, is that we never capitalise on openings and mistakes, never. If we go to play the early ball, we screw it up, if there's a chance to put an early cross in when the defenders are flat footed, we don't do it and we sit so deep that when Rondon receives a hopeful punt he has 2 central defenders and 2 defensive midfielders around him while blue and white shirts are usually at least 20 yards away.
All of the above means that when we do actually get that one opening and a chance is made for him the pressure is on him so much to get it right.
When we get chances to catch teams out, Sess tries one trick too many, Gardner is just awful, Yacob generally needs a playmaker (we don't have any) nearby and McClean is hit and miss.
We need to upgrade Sess, McClean, Morrison and not start Yac and Fletcher together AND stop playing so deep before we see an improvement in Rondon's goal return.
I'm by no means saying the above are bad players but you have to build a team around goals (goals = wins) and we need our "attacking" players to fit our 12 million pound striker.
I'd be happy with Fletcher or Yacob alongside Morrison but ultimately we need an upgrade on one of them. Then the three attacking midfielders need to be a proper winger on the right (Phillips from QPR would be great) who's powerful and puts in early balls, a more dynamic 'in the pocket' player like De Guzman or even Sess (Morrison is even ok here but not with Yacob AND Fletcher behind) and i accept McClean on the left but i do think he lacks the quality we need, although tip of the hat to him, he works 'ard and he has improved vastly and does offer value for money.
So the cheapest way of improving Rondon in my eyes would be:
Fletcher/Yacob Moz
Phillips/New winger Sess/New no.10 McClean
