The 19-year-old is currently on loan at Swiss Super League side Sion, where he has made an impact coming off the bench, scoring six goals as a substitute. His contract with Gladbach runs until 2028, and Sion hold a €3.5 million purchase option — a fee the Swiss club are not expected to be able to meet.
Boteli joined Sion last summer after struggling to force his way into Gladbach's plans, having previously turned down interest from Manchester United, Everton and Juventus to stay in Germany. He was the top scorer in the Under-19 Bundesliga during the 2023-24 season with 19 goals in 19 games, but found regular first-team football harder to come by in the Regionalliga.
His form this season has rekindled interest from elsewhere. SC Freiburg, Brentford and Swiss side St. Gallen are all reported to be tracking the Swiss under-21 international, alongside the newly reported interest from Brugge.
Whether Boteli returns to Gladbach's first-team picture or moves on permanently in the summer remains open. The Bundesliga side will be aware that a player who once attracted attention from some of Europe's biggest clubs has rebuilt his confidence in Switzerland, and with a buy option unlikely to be triggered by Sion, they retain control of his future.
Boteli will hope a strong finish to the season gives him clarity on where he plays his football next. There is no shortage of options.
