The Danish defender has been delighted with the effect Tim Sherwood's appointment has had on the club.
A dismal run of two wins in 21 Premier League games led to last month’s departure of the much-maligned Paul Lambert, with Sherwood taking over a side marred in 19th-place and in desperate need of a lift.
The effect wasn’t immediate, as Villa would suffer straight defeats to Stoke and Newcastle in his first two games in charge, but three consecutive wins since have lifted the club to 16th in the table and sealed a place in the FA Cup semi-finals.
The team now looks to be re-energised under the former Tottenham Hotspur boss and no more so was that evident than in the weekend’s 4-0 thumping of Sunderland, when the likes of Christian Benteke, Gabriel Agbonlahor and Charles N’Zogbia put in the kind of attacking performances which were all too rare during Lambert’s reign.
Okore is more than optimistic about their chances of avoiding relegation as a result and believes all the credit needs to go to Sherwood for inspiring their mini revival.
“The mood at Bodymoor Heath is electric,” he said. “The atmosphere mood is really high. Everyone is happy. That helps us go out there and really perform and do what we do best. That is really nice
"The gaffer has been great. He has come in with positive energy and really gone out there and said 'look guys, I really believe in this and I want you to believe it too. If we do this together, we can achieve the goals we set.’
"He has so much passion. It rubs off on everyone - it has with the fans and the players. Every time we score, he is so happy on the sidelines. That's great to see.
"He's inspiring. That helps to get us on board with his vision. I think that passion will continue. He is very dedicated too. He is putting his own mark in training and games."
