I am little disappointed with Christopher Nkunku transfer because his ability for Chelsea player in next season, actually Chelsea have inconsistency performance in this season and drop from top fourth standing position, they need new center forward can help them reach UCL position zone.
I think it's lot more complicated than that. Nkunku is a crucial player for Leipzig and they need him this season. Also lot of clubs have him on the list so lot of clubs would have been in race for Nkunku in next transfer window so Chelsea just booked him for next season. Nothing to disappoint there. I think they can still work out well with what they have got this season.
