Aston Villa boss Dean Smith says assistant coach John Terry will be key against Tottenham.
During his 19-year playing career with Chelsea, Terry worked under Tottenham manager Jose Mourinho for almost six of those, winning three Premier League titles, the FA Cup and three League Cups together.
Asked if he would be picking Terry's brain ahead of the game, Smith replied: "I have been picking JT's brains for the last 18 months!
"Hopefully the combined brains of myself, JT and Richard can overcome Jose.
"JT's been his captain twice at Chelsea and they've won a lot of trophies together. They've got a deep respect for each other.
"JT's openly spoken about the admiration he has for Jose as a coach and a person when they were at Chelsea.
"But the dynamics are different now. He's on my bench and he's sat behind me giving me bits of information that I'll need.
"We'll try and plot the downfall of one of his ex-coaches."
