Strachan was assigned the task of building a squad fit for a return to the Premier League on his appointment, and made it clear he was ready for the challenge having left Celtic at the end of the previous season.
"I don't need to be here and I don't have to be here. I'm here because I want to be here," said Strachan on his arrival.
"When I left Celtic I told everyone close to me that it would be very difficult for me to retrace my steps in terms of the excitement there.
"I felt I had to do something different. I have a chance of something different here."
Strachan soon set about adding a Scottish spine to the Middlesbrough side, bringing in Stephen McManus, Barry Robson, Willo Flood and Scott McDonald from former club Celtic, and Aberdeen forward Lee Miller, as he surrounded himself with familiar faces.
However, by then the former Coventry and Southampton boss had endured a disappointing start to his reign, opening with a 1-0 home defeat by Plymouth, as the club drifted from fourth place in late October down to mid-table by the time they lost the final game of 2009 against Barnsley in late December.
Strachan won only 13 games as manager of Middlesbrough
The second half of the season saw Middlesbrough weakened by the departure of winger Adam Johnson to Premier League side Manchester City, and results continued to waver from a 2-2 derby draw with Newcastle and a 2-0 win at home to Queens Park Rangers, to defeats at promotion-chasers Blackpool, Nottingham Forest and West Bromwich Albion.
Having missed out on the play-offs last term, Strachan set to work rebuilding the side during the summer, once again turning to Scotland to sign Rangers duo Kris Boyd and Kevin Thomson, as well as Charlton midfielder Nicky Bailey and Estonia winger Tarmo Kink.
But impressive performances in beating Burnley and Reading were punctuated by a home defeat by Ipswich and a rotten run of form away from the Riverside which has seen four defeats from five matches in the Championship.
Injuries to key players including Thomson and captain Gary O'Neil dented Boro's strength, while Boyd has struggled to replicate his Scottish Premier League form in the Championship.
With dwindling crowds and a media outcry following a 'curt' post-match interview following a draw at home to Portsmouth, the final straw for Strachan came in Saturday's defeat by Leeds.
Steve Agnew has been given responsibility for all first team matters until a new manager is appointed.
