Nottingham Forest boss Steve Cooper finds himself under pressure after defeat to Brighton yesterday.
The Daily Mail claims the relationship between Cooper and owner Evangalos Marinakis has become strained.
Marinakis wants to see results improve after back-to-back defeats. Forest's next three games are against Everton, Fulham and Wolves - who are all located in the bottom half of the table.
Despite the claims, Forest owner Marinakis is expected to give Cooper time to right the ship.
Forest are 14th in the Premier League table and eight points clear of the drop zone.
