Anderlecht chief Herman van Holsbeeck admits they face competition for Watford midfielder Sven Kums.
Kums has spent the season on-loan with Udinese, but is expected to be on the move from the Hornets this summer.
Anderlecht are keen, but Van Holsbeeck says: "We have been doing some homework for a while, and Kums is indeed an interesting player, he could cover Youri Tielemans' departure.
"But we are not the only club to compete. All top clubs in Belgium are interested in a player of his profile. We will see what we can do, we'll try to see if he wants to come.
"There has not been any contact with him personally."
