Kevin MacDonald is already braced for the up-and-down nature of being a manager as he declared his interest in replacing Martin O'Neill in the Aston Villa hotseat.
MacDonald has informed Villa owner Randy Lerner he wishes to be considered for the post on a permanent basis after operating for three weeks and five games as caretaker boss.
The former Liverpool midfielder made his decision in the aftermath of Sunday's 1-0 win over Everton. Lerner has been full of support for MacDonald and put him under no pressure to make a quickfire decision.
But MacDonald is under no illusions as to how quickly he could go from hero to zero given the pressurised and results-orientated nature of modern-day football.
He said: 'I know that managers, from week to week, if they win a game they are great. But if they lose a game everybody dissects it. I know how tough the football industry is.
'Every time you appoint a new manager it is a major decision at any football club. Are you getting it right, is it going wrong?
'You only get something like three games in the Premier League don't you and then you are a terrible manager? So every time you have to appoint somebody, it is a major decision.'
MacDonald admits he thought carefully about putting his name forward as a candidate to take over from O'Neill who quit five days before the start of the new campaign.
He said: 'I'd like to think that I actually think about all things,whether it is football or anything. I was not naive in thinking thiswas going to be an easy decision to make. I am aware of how big adecision this is.

'But the staff here have been fantastic. They have been very, verysupportive and they are all keen for me to want to be involved.
'When I've spoken to family and people like that, they have alwayssaid 'make your own decision - but you have worked hard to get tohere'.'

MacDonald has the support of senior players such as skipper StiliyanPetrov, Luke Young and James Collins who have all spoken publicly abouttheir admiration for him in recent days.
Collins said: 'Kevin has been at the club a long time and has the total respect of the players. All the players have worked with him when they have been coming back from injury in the reserves.
'It would be great for him. There would be no grumblings coming from Aston Villa and I think he has done a great job. We have all got the highest respect for him.
'He told us, coming off the back of a 6-0, we had to show some fight in front of our home fans. He made sure we knew it was a big game. He gave us the rallying cry and we responded.'
He has been a key member of developing a crop of promising youngsters as Villa's reserve-team coach.
