Roger likes Delpo - many reasons, 1st Delpo likes Roger - idealizing him and so on, Roger seems to like people who are in public saying how Roger is best and so on - Delpo always is praysing Roger, i would say from top 10 Delpo is the one which Roger likes most
RAfa- well it was mentioned many times, thier rivalry and media attention - they seems to get along, but i think they are not friends, they respect each other as big name in tennis and tough competition, but that´s it
Nole - not much to say, incidents, like DC, MC yelling to Nole´s camp and everything, i think Nole always liked Roger and was trying to get along with him, just Roger doesn´t like him for many reasons, they now also respect each other, and i honestly beleive Roger like him more and just is aware of fact Nole is good and trying to get along, but nothing more
ANdy- well this changed dramatically, Murray few years ago had talks like he wants to beat Fed and so on, but lately really Roger´s interviews about Andy are surprisingly nice - someting happened there between them off court, maybe Andy is supporting Roger´s decisions on board, who knows, but Andy right now i think get along with Roger
Tsonga- Roger seems to be popular among frenchmen, he speaks their language, but don´t know another reason, but Jo and Roger are getting along i think
Berdych- not much to say - Roger´s big career losses came to Tomas when nobody was expecting them - Olympics, Wimby10, USO and so on.
Ferrer- Roger never lost to him, Ferrer is prasing him, but his limited english and personality don´t think make them friends, but at least we can say Roger doesn´t have vs David for sure
Don´t have time to go to more players, but from top guys Delpo is Roger´s favourite kid i think
