Cahill, who arrived at Stamford Bridge from Bolton in January, is likely to start alongside Luiz when the Blues take on Bayern Munich in the Champions League final on the 19th of May, as the club"s captain, John Terry, is suspended.
"I"m still bedding in and getting to know the players, but I"ve got to know the likes of David Luiz pretty well who"s a great character, and also the younger lads like Ryan Bertrand," the England international told Chelsea TV.
"The more you play with someone the more you get to know their game.
"I think our relationship will grow, [David Luiz] is a fantastic player and since I"ve been here he"s been brilliant, knowing his game more than I did before I joined obviously helps, as it does with him knowing mine better."
