It has been reported that Warburton was made the offer by Arsenal before he was appointed the Forest boss and after his departure from Rangers.
The Englishman and Scottish Premiership giants Rangers parted company in February, and he was appointed the Forest manager earlier this week.
“Warburton held talks with Arsenal’s chief transfer negotiator, Dick Law, after leaving Rangers last month but made it clear that he wanted to stay in management rather than return to youth development, the area in which he started his career at Watford,” adds the report in The Times.
Warburton’s (reported) rejection of Arsenal suggests that he is very serious about his managerial career.
The 54-year-old is relatively young in his managerial career and has been quite successful.
The Englishman did a very good job at Brentford and guided Rangers from the Scottish Championship to the Scottish Premiership at the end of the 2015-16 season.
Forest are a massive club and one of the biggest in England, but Warburton’s job is going to be hard.
The Reds are in real danger of going down to the League One at the end of the season.
Warburton’s side will return to action on Saturday afternoon when they take on Derby County at the City Ground in the Championship.
