It has been a breakthrough year for 20-year-old Alexander Zverev, who has climbed all the way up to third in the world rankings after claiming five singles titles in 2017.
Three of those five titles were on hard courts with one of those indoors so he is certainly comfortable with this surface and environment.
Zverev leads Cilic 3 - 1 in career head-to-head meetings and has notably won the last three, including their meeting in Madrid earlier this year.
Cilic is making his third appearance at the ATP World Tour Finals but will be looking to improve on previous showings as he has never progressed beyond the round-robin stage.
The Croat has been in solid form coming into this tournament, reaching at least the quarter-finals in his last four tournaments, three of those being semi-finals.
Cilic may fall behind Zverev in most statistical markers in 2017 but he does edge the German in return games won on hard courts - 23% vs 21%.
Alexander Zverev has won six titles in his career and five of those have come in 2017.
Alexander Zverev leads the head-to-head against Marin Cilic by three matches to one.
Alexander Zverev has a 73% win ratio in 2017 compared to Marin Cilic's 69.8%.
Marin Cilic has won 17 titles in his career but only one of those has come in 2017.
The last three matches between the two players have all gone to a deciding set and Zverev has won all three.
The two players have met once indoors and Zverev won that match 7-6, 7-6.
Four of the 10 sets played between the two players have gone to tie breaks.
This could be a closer match than some of the statistics suggest as Cilic has been playing slightly more consistently than his opponent in recent weeks. Don't be surprised to see this go to a deciding set but ultimately Zverev has to be favoured on account of his superior head-to-head record and overall greater level of play in 2017.
