@toshj Dean Smith's heavy favourite to take over. Would he really leave Brentford?! I can't see it myself, he's building something good there
There are lots of reasons to go and lots of reasons to stay.
Go:
1) We don't pay him very much as far as Championship managers/head coaches go. He'd make a small fortune manager you lot, and it's something that should always consider
2) He's a Villa fan, so this is possibly the drop he always dreamed of taking, and he'll be able to move back home to the Midlands.
3) Massive club, big fan base, biggest side in the division, etc.
4) It's no secret that he's had a few interviews with other sides since he's been with us, so I'd expect him to want to speak with him
Stay:
1) He's a Head Coach, not a Manager, so is simply a cog in a large machine. He has one of, if not the best, support systems and infrastructure behind him. We have access to arguably the best and most advanced data, statistics and analytics in world football, and the backroom staff list is exceptional
2) He knows he has a great deal of support and security in the job. A one-win-in-nine-games run most certainly wouldn't result in a sacking if the stats say he's not doing too badly. He knows that a poor run at Villa and the knives will start getting sharpened
3) Budget. We've got a small but well-used budget. You've got a massive but terribly-used budget tied up in big contracts for ageing players. Which is better and which is worse? I've no idea to be honest, but it may depend on whether he can free up some cash spent on those big wages
4) He's surrounded by forward-thinking and progressive people at Brentford. At Villa (no offense meant at all, honestly), but he won't have that at Villa. With the budget you lot have, you should have walked this division by now but you're a poorly run football club with little in the way of identity currently. It's one thing he's good at; bringing a group together and he's a brilliant coach, so that would play in your favour as you've got the size and scope to become a huge club again.
He's a streaky coach. We go on 15 game unbeaten runs where we look brilliant, and then don't win for 2 months. The fact that the Villa job is a massive rebuild which requires top to bottom restructuring - but with a big budget and a sensible manager... what a job that would be. However he's not been in charge of much at Brentford for a few years (i.e. doesn't have to focus on transfers, contracts, health/fitness coaching, youth group, etc.) so there would be a question as to whether he wants to do that, and can he do that?
I've really enjoyed him as our Head Coach. We had a great deal of uncertainty at the club before he joined, and it's known that the owner wasn't particularly enjoying the club somewhat. Dean Smith steadied the ship, completely changed the attitude around the club into an overwhelmingly positive one and the players loved being coached by him and playing for him. We also play arguably some of the best football in the division (when we're in our stride), but like every team in the Championship, we can be decidedly average and weak at times. Tactically he's merely average, and possibly the good work of the backroom team appears to be mostly Smith's work at times.
I think we'd like him to stay but are relaxed if he goes - we've already got his replacement in Thomas Frank, one of our assistant managers and former Brondby manager. I've really enjoyed his time at the club, but he'll need a great deal of patience from your fans and, more importantly, the owners.
