Sherwood has come in as manager after Paul Lambert was sacked and he’s facing a real battle to keep the club in the Premier League over the rest of the season.
Clark’s comments in a blog for Villa’s website suggest that the first change Sherwood has tried to make is getting players to keep their chins up at all times.
“We have a new manager in Tim Sherwood - and the number one thing with the gaffer is he's unbelievably positive. That's his outlook,” wrote Clark.
“He's very hands-on. He's spoken to the lads individually - what he expects and what he wants. He's addressed the group too.”
The main affect a positive attitude will have on the club is encouraging Aston Villa’s players to show a little more determination in big games and not be afraid to take risks.
It’s a good approach from Sherwood because when he was appointed, he was faced with a situation where the team was used to losing under Lambert and may not have given themselves much of a chance in big games.
“He gives you positive feedback and he's not shy in letting us know what we need to improve. He's very honest with us.”
There was a setback last weekend with the defeat at the hands of Stoke City, but if Sherwood and the players work well together throughout this week, there’s no reason they can’t react in the right way.
Things will be a bit easier around the club if they can register a win at Newcastle United this weekend and that should be enough to help the side out of the bottom three.
