Keenan guided the Dublin club to a host of National titles before being axed back in 2011.
“I do not bear grudges against anybody in Killester as I think life is too short to be carrying a chip on your shoulder,” said Keenan.
“Over the years I have enjoyed working with some great players at both clubs and I still have a big appetite for the sport. I have had some fantastic years in both on and off court.”
Looking ahead to the game, Keenan believes it’s a must win one for his side if they are not to lose vital ground on the top three.
“Realistically I think if we fall three games behind UCC Demons it would take some pegging back but on the other side of coin Killester will also be determined not to lose.”
Injuries have been unkind to UL this season but Keenan reckons the return of Scott Kinevane is a huge boost to his team.
“Killester have a lot of depth but when we have Kinevane in our line up it gives the team a huge lift with his pace and vision.”
Leaders C & S UCC Demons host basement side Moycullen on Sunday at the Mardyke Arena hoping to ring in the New Year with an unbeaten league record.
Demons will be without Spanish ace Christian Anon and point guard Daniel O’Sullivan.
“We have enjoyed the Christmas break but the lads have stayed focused and hopefully we will have enough on the day against Moycullen,” said coach Colm O’Reilly.
DCU Saints will be hoping to avenge their recent cup defeat when they host Bord Gais Neptune at the DCU Sports Complex.
Neptune welcome back point guard Roy Downey but the Saints coach David Donnelly will be hoping his team can rise to the challenge.
“We had a chance to defeat them in the cup and a loss is unthinkable if we are to keep our league aspirations on track,” he noted.
Team Montenotte regular season title hopes were dashed when losing at home to Killester last week and they will be hoping to get back to winning ways when they entertain Liffey Celtics at Upper Glanmire Sports Centre on Sunday.
The Cork side were fortunate to defeat the Kildare side when they met in the first round with extra time deciding this enthralling tie.
For the Montenotte coach Paul Kelleher playing stringent defence will be his team’s New Year resolution.
“We were in control against Killester but suddenly dropped our guard and I am hoping lessons will be learned from that blip,” Kelleher said.
