Frank Ronstadt has swapped Kaiserslautern for Viktoria Köln, sealing a late loan move that gives the club both reliability and flexibility.

The 28-year-old German-Ghanaian defender arrived in Cologne on deadline day, ready to bring his energy and experience to Marian Wilhelm's side.

Ronstadt, who grew up in Hamburg and came through the youth ranks at Hamburger SV, has built a career on adaptability.

Though capable of playing in several positions, he thrives most on the wing, where his pace and work rate shine.
