Brendan Rodgers' first game as Celtic boss ended in some embarrassment as his side lost 1-0 to Lincoln Red Imps in the first leg of their Champions League qualifier at the Victoria Stadium in Gibraltar.
Here, Press Association Sport looks at five things the Hoops manager will need to change.
1. Cut the squad
The Celtic squad is still too big and a clear-out is required. Rodgers has only brought in Moussa Dembele and four strikers have left but players like Scott Allan, Emilio Izaguirre and new boy Kristoffer Ajer were not even on the bench in Gibraltar with Gary Mackay-Steven, Kris Commons, Stefan Johansen, Dedryck Boyata and Jozo Simunovic out through injury. Returning loanees such as Liam Henderson and Darnell Fisher also sat in the Victoria Stadium stand.
2. Bring in new faces
While needing to prune his squad, Rodgers also needs to bring more quality in and a 'big name' would help appease the Hoops fans who are looking for marked improvement from the Ronny Deila era.
3. Find a reliable centre-back pairing
In the absence of the injured Boyata and Simunovic and with out-of contract Charlie Mulgrew still in talks over a new deal, Erik Sviatchenko and Efe Ambrose were the centre-back pairing against Lincoln Red Imps. Sviatchenko is not the fastest and the error-prone Ambrose continues to cause uncertainty and struggled at the goal.
4. Inject pace
Notwithstanding the dreadful artificial surface at the Victoria Stadium, too often Celtic's play going forward was laboured, allowing the home side to get back and stifle their attacks. James Forrest provided some pace when he came on but his contract expires at the end of the year, while Patrick Roberts was not used.
5 Keep Leigh Griffiths in the centre
Griffiths scored 40 goals last season as a centre-forward but was shunted wide against Lincoln to accommodate new signing Dembele. The Scotland international struck the bar twice from central positions, where he does his best work, but Rodgers may not want to play with two up front. A resolution is required as Griffiths' goalscoring was the one bright spot for Celtic last season.
