But he admits Chelsea manager Maurizio Sarri remains a fan of the youngster.
Assistant manager Zola pledged that Hudson-Odoi will get more chances in the future – but still needs to do better.
Chelsea rejected three bids, the largest of around £35million, from Bayern Munich for Hudson-Odoi during the January transfer window.
They also turned down a transfer request from the England Under 17 World Cup winner, who had made it clear he wanted a move to the Bundesliga.
Since the January widow closed though, manager Sarri has given the youngster just 19 minutes of action, 13 minutes in the 5-0 win over Huddersfield, and six on Thursday night in the 2-1 Europa Cup win against Malmo in Sweden.
