Tennis is full of young talent, with teenagers as young as 15 achieving great feats on the circuit. Here are five of the best to look out for in 2015.
Croatian Coric is just 17 years old but is likely to be a name on many people's lips this week after his stunning victory against Nadal in Basel.
A former number one junior, he is now the youngest player inside the top 100. He has already reached seven singles finals winning six of them and he seems destined for greatness.
He is an all court player, and rarely doesn't get balls back into play forcing his opponents back behind the baseline. His groundstrokes are hard and penetrating and his serve can be a strong weapon as long as he keeps his first serve percentage high.
He has great court coverage and his shot choice is superb. His match against Nadal isn't the first time he has impressed against quality opponents. He has had impressive wins against top 50 competitors such as Lukas Rosol, Edouard Roger-Vasselin and Jerzy Janowicz before his deep run in Basel, only ended in a tight three set defeat to in form Goffin.

Coric's playing style has been likened to Novak Djokovic, but only time will tell whether he match his achievements.
Jarmere Jenkins is a player who has flown under the radar of many people. He is now 23 so older than some of the breakout teenage stars, but he is arguably in the form of his life. He is ranked 258 in the world but he is in staggering form in both singles and doubles.
In his last tournament, the Australia F8 futures he won the singles title defeating five Australian's on their home soil including Luke Savile who is ranked inside the top 180. He also won the doubles tournament partnering Mitchell Krueger.
He has reached nine future's finals, winning five of them but three of those have come in the last month. He has won a series of American accolades including being named the 2013 Intercollegiate Tennis Association National Player of the Year.
He is an incredible athlete, and his serve is consistently strong. His net play is solid and he is a great retriever, reaching many balls that some wouldn't get too. While he is prone to the occasional second set lapse he usually recovers strongly in the third.
He is yet to be tested against the best in the world but as he moves up the rankings we should see that materialise in 2015.
His most recent victory came against world number 114 against Japan's Go Soeda in straight sets, and that could be a platform to see him move up to ATP events against quality opposition.
Cici Bellis is aged just 15 but is already making a huge impact on the tennis scene, particularly recently as she won her first two titles in October of this year. She is ranked just outside the top 250 but is thought of as the second female junior player in the world.
In August she won the USTA Girl's National Championship which enabled her to secure her wild card into the US Open. She became the youngest player to win a match at the US Open since 1996 defeating Cibulkova who was ranked 13th in the world at the time.
She is a consistent player, and while she can be aggressive she seems to always pick the right shot in which to step in on. She is an all court player and is good at the net, but her serve will have to improve if she wants to compete at the very top level.
With her being just 15 she has plenty of time to add to her game and I expect an entertaining Grand Slam run on home soil at some point in the coming years.
Omar Jasika became well known amongst tennis fans when he won both the Junior boy's singles and doubles titles at the US Open this year, becoming the first in 28 years to achieve that. T
he 17-year-old Australian is now ranked inside the top 700 and he reached his first singles final, only to be defeated by Jarmere Jenkins in three very tight sets.
While Jasika is not the tallest, he is athletic and a great mover on the court. His groundstrokes are consistently deep and punishing, forcing his opponents back and into errors.
He is a hard worker and hits the ball with impressive pace and direction which can cause players to burn out when facing him. He will be hoping to use 2015 as a breakthrough year in terms of tournaments as he looks to gain more experience and earn his first singles title after some impressive runs to the semi's and one final of the futures.
Xu Shilin is aged just 16 and is ranked as the best junior female tennis player in the game. She is good in both singles and doubles and has had tournament success in both despite her young age.
She has reached four finals, winning three of them, with both her singles wins coming in December 2013 in Hong Kong.
At the 2014 Summer Youth Olympics she won the gold medal, defeating Belarusian Shymanovich in straight sets. Her singles ranking is impressive for her age, as she is in the top 450 in the world.
She has made a few sporadic WTA appearances, with her first being an impressive victory over Konta in straight sets. She has also taken player such as Lisicki and Riske to three sets.
She possesses many weapons including hard, flat groundstrokes which keep low on the court and are difficult to get back over the net. Her serve is powerful and she is capable of hitting several aces in a match. She does not make many mistakes and she has an extremely effective passing shot.
Her return of serve is also strong, and her whole court game looks to be solid with little weaknesses. 2015 will be an important year particularly if she can win a junior Grand Slam title.
