Former Crystal Palace boss Patrick Vieira remains under consideration at Nottingham Forest.
The Daily Star says he tops Forest's list of possible replacements should Steve Cooper be moved on.
Forest owner Evangelos Marinakis has given Cooper a vote of confidence over the last week.
Forest meet Manchester United today as they struggle through an eight game winless run.
Vieira, 46, is aware of Forest's interest but favours waiting until the summer before returning to management.
