Nigel Hasselbaink has revealed he and St Johnstone team-mate Stevie May are working on their strike partnership on and off the park.
The pair have struck nine goals between them in the last seven games ahead of the William Hill fourth-round clash with Livingston at McDiarmid Park.
Hasselbaink said: "I'm really enjoying it. We are both doing well and we are doing ok in training as well.
"We are getting a good partnership and we speak to each other loads as well so hopefully we can keep this run going.
"I speak loads to Stevie about how we can get better, how we like the ball, when he likes the ball into his feet and when he wants it in behind and what we can do to make it harder for defenders.
"He is a smart boy, he is strong and quick. He can keep defenders busy and I can do the same."
Saints have only lost one of seven Scottish Premiership games at McDiarmid Park this season and manager Tommy Wright is glad of the home advantage against a side which put five goals past Championship rivals Morton last weekend.
"I never read too much into who are favourites," Wright said.
"All I know is that we'll be up against a team that will be trying their damndest to beat us, so we have got to make sure that we're right.
"We have approached games against teams from leagues below us in a good manner ever since I've been at the club.
"It's important that we have the right attitude because if we don't then they have enough armoury in their tank to hurt us.
"They have some good experienced players and a mixture of young players as well and they do try to play football, so that makes them dangerous opponents."
Wright, whose side have a League Cup semi-final against Aberdeen to look forward to, added: "We know it's going to be a difficult tie.
"We are pleased it's a home tie because obviously our home record has been better, although we have done well away from home in the cups this year.
"But we're at home and the emphasis will be on us to take the game to them and I think that will suit us.
"We are looking forward to it. The Scottish Cup is the premier cup competition in the country. There is always that bit of magic about it and we want to progress in it."
Livingston have been given clearance by Celtic to include loan signing Patrik Twardzik, but Mike Mampuya (knee) and Mark Burchill (calf) remain sidelined.
Recent signing Nejc Praprotnik will also miss out due to a knee injury, while Livi manager John McGlynn is delighted to be heading to Perth on the back of a 5-1 win at Morton.
McGlynn said: "I have a lot of respect for St Johnstone and their manager Tommy Wright.
"They are having a good season and are favourites to beat us, however we are looking to cause a shock.
"Our win, and our attacking performance last weekend, has given us a lot of confidence."
