To the beginning of the 2004–05 season, Lell was loaned to 2.
Bundesliga club 1.
FC Köln, where he had a disappointing season.
After the 4–2 loss to Wacker Burghausen on the second matchday, Lell fell out of favour with manager Huub Stevens.
He earned a mere sixteen league appearances over the course of the season.
The season however wasn't entirely without successes for Lell.
In Köln's second league match against Wacker Burghausen he scored a goal.
Beyond that, he earned two caps in the DFB-Pokal, and eight for the reserves in the Regionalliga Nord.
After the "Billy goats'" successful return to the Bundesliga for the 2005–06 season, Lell earned considerably more appearances, especially during the latter half of the season, during which he advanced to the regular starting formation.
He finished the season with 26 league appearances and a cup appearance.
