Albarn, who is currently topping international charts with his GORILLAZ side-project, has announced the British hitmakers will release new material with him taking over Coxon's duties.
But he openly admits he falls short of Coxon's fret skills - and has no idea how he will be able to combine his frontman persona with his new instrumental obligation.
He says, "I think the problem is I find it difficult to sing and play at the same time. Graham has always been able to do it. I just can't. I can't put them together.
"By being at the back, I can actually manage it - headphones on, head down, really concentrating. But I can't do that and worry about connecting with the audience."
