He's too high up the pitch, which will encroach on Ronaldo's roaming space, but also - and, for me, more of an issue - defensively, Ronaldo will do next to no work, which is acceptable, but Bruno's defensive legs and contribution to any central press is crucial without world class central midfielders sweeping up and recycling the ball behind the forward line.
There's already an issue with Bruno sitting too high compromising our midfield, and that's with more defensively responsible central forwards - in Cavani, Greenwood and even Martial - than Ronaldo will, or at 36, could be. Please note that pointing this out about Ronaldo isn't a criticism of him, and further to that, his energy is better conserved and utilised thinking about his next action that can hurt the opposition.
Further to the above, in terms of being available for the pass as well as turning and progressing the ball forward, he cannot continue in a support striker role with Ronaldo being superior in almost every facet when it comes to receiving the ball and turning that into a viable goalscoring opportunity. Bruno needs to be the guy looking to supply rather than being on the end of so many balls.
Having two forwards sitting high and not dropping deep or into rank to aid the midfield is not viable, well, unless you have a world class engine behind them in terms of a runner and retainer - something like a prime Modric and Essien, for example, which no club has at the moment.
For myself, Ronaldo arriving means Bruno has to play 15-20 yards back, get involved in the build up by both being available and also being more balanced in using his legs and energy. His shooting opportunities should reduce somewhat, and his goals might reduce, but goal involvements and contributions via passing should go up.
In your opinion, does the arrival of Ronaldo almost organically sort out issues with the spine of the team, or will Bruno be left to the same devices as he has had during his support striker/much-less-of-a-midfielder run? If Bruno stays where, and, as is, do you think that the team as a whole can cope?
I haven't watched Portugal outside of the Euros where Bruno seemed to struggle to get involved with their build up play - is that an issue for Portugal in general with both Ronaldo and Bruno on the pitch, or something that came out of the blue during the tournament proper?
