The Scottish Premiership side fell to a shock defeat in the first leg.
Celtic manager Brendan Rodgers
Lisbon Lion Bertie Auld has admitted that he was surprised that Brendan Rodgers decided to pick Efe Ambrose in his starting line-up for Celtic's Champions League tie with Lincoln Red Imps, The Scottish Sun reports.
The Nigerian was selected to start alongside Erik Svaitchenko at the heart of the Hoops' defence for what should been a regulation win in Rodgers' first competitive game in charge.
Celtic's Efe Ambrose
However, the Bhoys were stunned as the champions of Gibraltar secured a 1-0 win in the first-leg, with Ambrose receiving most of the criticism following the defeat.
And Auld has claimed that there have been enough warnings during the centre-back's time at Parkhead to suggest that such a result was possible with him in the team.
"It's never just about one player but I was surprised to see Efe in the team," he told The Scottish Sun.
"He should have done so much better at the goal and he'll know that too.
"Efe always has that in his make-up and he'll always play that way.
"It's up to the manager whether or not he's prepared to put up with it."
Following Ambrose's horror show in last season's Scottish League Cup semi-final clash with Ross County in January, the defender started just four more games before the season came to an end.
And while it would be unfair to suggest that his lack of appearances from that stage was the only reason that Celtic went on an excellent run of form until the end of the campaign, the defence that Ronny Deila called upon for much of that time did look a lot more assured.
And Auld will be hoping that Rodgers comes to the same conclusion that Deila seemed to come to that Ambrose is not reliable enough to be one of the side's main options.
