Talk about body shaming
Glad I'm not playing, crikey. Not sure about Lui; Konrad could lose some weight, but this has been a constant thing throughout his career.
How many mature players have you seen fundamentally change their physique? It's highly unlikely to happen.
I imagine his ability to contribute in games would be improved if he was leaner, and I agree that for professional sportspeople not to be in the best physical shape they can be is poor.
For me, it's more about how we use him too - definitely should be kept on the right, and I'd like to see us creating more room for him rather than just giving it to him in hopeless positions and standing back while he runs at three defenders. The team needs to work better with him IMO.
