Serena William' coach and rumored boyfriend Patrick Mouratoglou posted a video on YouTube highlighting "her incredible year," leaving many fans wondering just how proud he is of her.

The video, published on Monday, chronicled high and low points in Serena Williams' tennis career in 2013.

Earlier this week, it was reported that the American tennis star is a likely contender to win the United States Sports Academy "Athlete of the Year" award.

Serena Williams is one of the 12 finalists for the 2013 Female Athlete of the Year Award, according to AL.com.

Jamaican sprinter Usain Bolt is in the lead to win the Male Athlete of the Year Award.

Last week, Patrick Mouratoglou was accused of being "conservative" with his Facebook photos in a recent comment, leaving many wondering if the French tennis coach will post more about his relationship and personal life.

"Patrick, you have been going the conservative route with most of your pictures for the past 11 months, but as the holiday season approaches, you deserve to carry the liberal label for one day and gave us a photo that many people are salivating to see on this blog," a fan commented on a recent picture he posted on his Facebook photo blog.

"The photo will speak a thousand words. Go for it Patrick, we will support you all the way."
