Watched him play in one match Peru vs Chile and here were my observations.
CB 2 Alberto Rodriguez - Braga/Seems strong in air/Good res/BB84?Stronger than Zambrano/Res82-83?/made a poor TW play/maybe not that high Ment?/Good TS..kept with Sanchez/80TS?/
So basically the 2 main points I'd be happy if you would look at would be his Balance and Res. IMO both of these current values are very poor for a top level CB. In the Serie A Siviglia has an 81, with a slightly bigger build, and is possibly the weakest CB in the league. Rodriguez has some serious strength to him, and by saying 84
I feel I am being somewhat conservative. Obviously you have your ladders...but in the Serie A there are very few CB's that low. They are all inexperienced, or not very good. Also with the improving of his Def recently & hopefully his response....there might be a need to lower his TW and Mentality. No suggested values...but they didn't seem to be his strengths.
