The Bhoys failed to get past the qualifying rounds last season, but the 38-year-old believes that they are more suited to making it through to the group stage this time around.
“He (Ronny) is going to be judged on his European stuff,” Craigan told BT Sport. “Last season Europe was probably a little bit too early for him.
“He didn’t get a chance to get across how he wants to play. Celtic are a lot more dynamic now, no doubt, and I think that that will suit European football next season.”
Just like last season, Scottish Premiership champions Celtic will have to to negotiate tough qualifying rounds.
Last season, after getting the better of KR Reykjavik and Legia Warsaw in the second and third qualifying rounds respectively, Celtic faced NK Maribor in the playoff round.
Although the Scottish giants drew the first leg of the tie 1-1 in Slovenia, they lost the second leg 1-0 at Celtic Park.
One suspects that Celtic manager Ronny Deila will be more prepared this time around for the Champions League qualifiers than he was last season.
The qualifiers kick off in July, and the Celtic players will have to regroup quickly in trying to reach the group stage of Europe’s premier club competition.
