1998-1999, no sponsor (This could have gone on to be the Third kit had Celtic qualified for the Champions league group stages in 1998, however no third kit, as required by UEFA, was needed as they were defeated by Croatia Zagreb)
Man Utd. wore a training top of the same design as their third kit that same
Treble winning season and this training kit clearly was meant to be utilised as both a training / third kit, with relevant sponsors and numbers added.
1999 – 2000
Again a training top that could have potentially been used as a third kit with the exact same spec and design, ie. Everton had a version of this design as a playing kit (in yellow) however Celtic never needed a third kit as they were in the UEFA Cup that season.
