Tournament favourite Federer confirmed his spot in the semi-finals with a hard-fought victory over young rival Zverev with his position secure regardless of the outcome here.
The Swiss dominates Cilic in career meetings having won seven of their eight encounters, including a straight sets victory in this year's Wimbledon final.
Federer may relax a little given the circumstances but he is still a heavy favourite and has the added motivation of moving closer to Nadal in the world rankings going into 2018.
Cilic's qualification hopes were ended after defeat to Jack Sock in the second round of matches, once again losing after being 3-1 up in the deciding set.
Although having nothing to play for, the Croat will be keen to put in a good showing against the six-time champion and end his season on a positive note.
He has lost seven times to Federer but he does at least have the memory of a straight sets victory over his opponent on hard courts, that coming in the 2014 US Open semi-finals.

Having already booked his place in the semi-finals and with his opponent's qualification hopes over, it will be interesting to see how Federer approaches this dead-rubber encounter with Cilic. The world number two's intensity levels may drop a little, but Cilic has struggled mentally in this tournament having allowed leads to slip out of his grasp in his opening two matches. Expect Federer to do a professional job and make it three wins out of three in the Boris Becker group.
