VIDEO: Djokovic gets trembles again during ATP Finals win over Ruud

Novak Djokovic was spotted midly shaking once more during his ATP Finals win over Casper Ruud.

Djokovic first experienced shaking in his match against Medvedev where he looked very exhausted. He was able to rally and win the match with his semi-final against Fritz rather comfortably. The shaking returned against Ruud in the final and while he was able to win that match comfortably, the shaking is something fans are starting to get worried about.

Djokovic played off it off after the win over Medvedev saying he was simply exhausted.
