Not sure how many watched the Rayo Vallecano game, but Ronaldo seem to be heavily involved in the buildup phase. He was taking positions in open spaces to receive passes and attempted alot of passes and through balls to players running into spaces. The passing was quite fluid and instantaneous, though not all passes came off successfully.
It was a clear indication that he was following ETH's instructions. Previously he would try to take potshots or dribble into space to attempt a shot rather than do any of this. Looks like the old dog is learning new tricks, which tells you about his attitude to adapt.
