Captain Christopher Trimmel dedicated the renewed derby triumph of 1. FC Union Berlin in the capital duel with Hertha BSC to a special player. “This victory is for you Isco,” he wrote on Instagram. He would no longer have needed the smiley with a kiss to further fuel the flirt of the iron with the highly decorated and currently clubless Spaniard.

The fact that Isco himself responded with a biceps emoji fueled speculation about a possible sensational transfer to Köpenick even more. “He’s coming!”, wrote fellow Trimmel player Timo Baumgartl.

However, it is unclear and open whether the Union professionals were just having fun. The broadcaster Sky had reported that the Berlin Bundesliga second had allegedly contacted the former Real Madrid professional. With the royals, Isco had won the Champions League five times and the Club World Cup four times. After moving to Sevilla FC last summer, the Andalusians were eliminated after just a few months, and Isco has been without a club since the end of last year.

“If Isco is associated with us, then we must have done a lot right,” said Union President Dirk Zingler on Saturday before the 2-0 win at Hertha. “That’s an honor for us.” The club is playing internationally for the second year, “we’re second in the table now, so players are now also dealing with our club who didn’t deal with us three or four years ago.” Ob Isco, who too 38 caps for the Spanish national team, that counts remains open for now.
