Hertha Berlin chief Michael Preetz admits keeping hold of Matteo Guendouzi is no guarantee.
On a straight loan from Arsenal, Guendouzi is already a starter for Hertha coach Bruno Labbadia's first team.
Since shaking off a positive coronavirus test while away on international duty with France U21, Guenzdouzi has played twice - including enjoying a first start in victory at FC Augsburg last week.
Labbadia is a fan and there is already growing calls for Hertha to explore the prospect of buying Guendouzi. The Frenchman has won praise for his performances in a defensive midfield role.
But Preetz says nothing can be rushed, particularly given the finances involved. Preetz stated to Kicker via Fussball Transfers: "Three months ago, Matteo's loan signing wasn't possible, but it was at the beginning of October.
"We are happy that he is here and that he enriched our game from the start. We'll see everything else next summer.
"How the prices will develop by then and what Arsenal is planning then, nobody can say today."
Hertha, after the 3-0 win at Augsburg, currently sit in 13th place on the Bundesliga table and are yet to win at home so far this season.
Guendouzi has a contract with Arsenal to 2022.
