As you mentioned, football is 11 vs 11 games, striker main role is to score goals, to which Ronaldo has been doing his job right.
We have disjointed team because most other players are not doing their job right. Midfielders are not doing their job of passing the ball around, involving in build up play, or creating. Winger is not doing their job of providing cross and chances, defenders are not doing their job of defending as a unit. Of course, attackers, including Ronaldo, are not doing their job to press as a unit too.
And these are mostly down to coaching too, Ole and his coaching team never setup our team right to address all these issues.
Our wingers are inverted forwards.
It should be Ronaldo who passes to them.
Strikers are not just pure goalscorers. Wingers can be the goalscorers of the team as seen by Ronaldo himself who was again an inverted winger/forward but not a central striker even in his prime. Who were then the strikers? Rooney, Tevez, Benzema, Dybala - player that could pick a pass.
Forget about the pressing, Martial wasn't a good presser - but played/positioned centrally enough and received the ball to feet, holding the ball up and linked up play with his passing which kept the centre backs busy even if he was easy to defend against.
Ronaldo doesn't even occupy the central areas alot of the time so it looks like we don't play a central striker on paper. Nothing that keeps the CB'S busy because no pressing. No ability to hold the play up with his back to goal. No passes or one two moments with the players around him.
Anyway, this was Ole's fault for not tactically understanding Ronaldo.
Every single manager - be it SAF, Zidane, Mourinho all the Real Madrid and Juventus managers - didn't get the best out of Ronaldo as a single central striker as the lead striker.
The only managers that did are arguably Ole and the Portugal National manager - which says alot in my opinion. Even the Portugal Euro final had him Ronaldo and Nani upfront with Eder coming on and scoring the winning goal.
Anyway, let's see where Carrick's tactical eyes are now.
Will he join Ole and the Portugal National manager - or will he join the more legendary managers of club football.
