Ea Lla Koto had a great season under the Belgian tactician, who guided them to a sixth-place finish in the Premier Soccer League (PSL) and Nedbank Cup triumph.
The performance of Stars' best players has caught the eye of some of the biggest football clubs in the country.
Stars midfielder Nhlanhla Vilakazi is set to join AmaZulu FC having signed a pre-contract with the KwaZulu-Natal giants earlier this year.
Recent reports have also indicated that Nyiko Mobbie is on the radar of Chiefs and Pirates ahead of the July-August transfer window.
The 23-year-old right-back was a consistent performer for Ea Lla Koto - making 30 appearances in all competitions during the 2017/18 season.
Eymael says it is very important for the club to keep its best players having qualified for next season's Caf Confederation Cup by winning the 2018 Nedbank Cup.
“It’s very important to keep all our best players, very important because we will be playing in Africa in the new season,” Eymael told Vodacom Soccer.
The 58-year-old tactician is also known to have attracted interest from Chiefs and SuperSport United, who are both searching for a new head coach ahead of the 2018/19 season.
“If you want to compete in Africa you must have a good squad. So Mobbie is still contracted to Stars like me, I’m contracted to the club," he said.
“But it’s very important to have all the best players remaining with the club though you never know what will happen. Its life, it’s like that," he concluded.
Mobbie, who was born in Xikundu village in Malamulele, Limpopo joined Stars' Youth Academy from his home-town's amateur club FC Basel in 2016.
He was elevated to Stars' first team during the 2015/16 campaign after doing well in the club's MultiChoice Diski Challenge side.
