Basel, the club where Charles Pickel started his career and made his professional debut, is reportedly interested in signing him, according to cuoregrigiorosso.com. Pickel, who has made 19 appearances this season and scored once, is also attracting interest from Sion, another Swiss club. Sion has put forward a loan proposal which includes an obligation to buy under certain conditions. The decision now lies with his current club, Cremonese, and Pickel himself, as they assess these offers in the final days of the transfer window. Basel will need to make a strong offer to persuade Cremonese to release Pickel, who is seen as a vital player in their midfield.
