Celtic have rewarded last season's top-scorer Scott McDonald with a new five-year contract.
The Australia striker enjoyed a stunning first season at Parkhead where he found the net 31 times for the eventual Scottish Premier League champions.
The 24-year-old joined the Hoops last summer from Motherwell.
"This is great news for Celtic," chief executive Peter Lawwell told the club's official website.
"It is well known that Scott loves playing for Celtic and he has a great affection for the club. He is also someone who performed brilliantly last season.
"Our priority is always to keep our best and most committed players and the board is delighted to support Gordon (Strachan) in his plans for the future by securing Scott on this long-term agreement.
"We will continue to do all we can to ensure that Celtic stays at the top of Scottish football."
