Now Celtic are in the Europa League can Brendan Rodgers create the legacy he desires by emulating the success of 2003?

Last month Brendan Rodgers was once again speaking of creating a legacy at Celtic as his successful tenure as manager continues.
"My job at Celtic is to add to the legacy so when the time comes for me to pass the ball to someone else, we have really added to the cycle," Rodgers was quoted by the Scotsman.
"What we have been working on is a real dominant cycle where we play football that brings joy to the supporters. When it gets passed on we hope this is looked back on as a really successful period.
"That's my job. There is a wonderful history here at Celtic and my job is only to add to that legacy."

Rodgers has certainly gone a long way to achieving that during his 18 months at the helm, winning the treble of Scottish Premiership, Cup and League Cup in his first season and on course to repeat the feat in 2017/18 having already won the latter again.
The Bhoys are also on a 67-match unbeaten run in domestic competitions in Scotland - the longest in British history.
Yet for Rodgers the missing piece of the jigsaw is bringing European glory back to Parkhead, something which has not been the case for some time.
The Northern Irishman did take the Glasgow side back to the Champions League this term, where they were handed a tough group draw alongside Bayern Munich and Paris Saint-Germain.

They concluded their return with a defeat to Anderlecht on Tuesday (December 5) which although meant five losses from six games, because of their superior head-to-head record with the Belgians finished in third and booked their place in the Europa League.
This second tier of European competition is where Rodgers could truly shine and arguably secure the Hoops' greatest campaign since they reached the final of the tournament back in 2003.
They will have to overcome teams such as AC Milan, Arsenal and Atletico Madrid to achieve it, but if the 44-year-old is serious about his legacy then the stage is set to truly create it.
