The striker is on-loan at United from Shanghai Shenhua and is wanted by the English giants in a permanent deal.
But Udeze told Brila FM: "At 31, what's left?
"Who does he need to impress? No one – I will jump at the Shanghai's offer immediately.
“£400,000 is a lot of money and Manchester United cannot afford to match that amount, so, for me, I will accept Shanghai's deal."
