After Monaco played a pre-season friendly against K-League team Incheon United today, Lacombe was quizzed about Park's future by the local media.
"I don't know anything about transfer rumours," he said. "Even if an offer came we have no mind to sell the player. but in football I think there is no such word as 'never'."
The friendly ended 2-2 at Incheon's World Cup Stadium in which Park came on as a second-half substitute. The French team were two goals to the good by the break thanks to Daniel Niculae and Argentinian star Alejandro Alonso.
Incheon hit back in the second half through a 50-yard strike from Do Hwa-sung and Lee Se-joo.
"We played well in the first half, made a number of chances and stopped their attacks," added the Frenchman.
"Our young players looked good but it's true that they are not experienced. Incheon's first goal came from our mistake but it was a very good goal."
