Deila has no plans to ditch philosphy
Ronny Deila promised to keep the accent on attack at Celtic but admits defensive worries in Europe have to be addressed.
The Hoops manager watched his side fight back twice against Inter Milan to draw 3-3 in the first-leg of a thrilling Europa League last-32 clash at Parkhead on Thursday night.
However, the Scottish champions have now conceded 22 goals in 13 European ties this season and will have to tighten up in the return game in the San Siro next Thursday night if they are to have any hopes of progressing further in the competition.
Ahead of the trip to Hamilton in the Scottish Premiership tomorrow, where midfielder Kris Commons will return after recovering from a hamstring complaint, the Parkhead boss outlined his philosophy.
"There is always a balance between attacking and defending," he said.
"But I would rather win 4-3 than 1-0. We want to attack and we want to be offensive but the goals we lost against Inter were too easy.
"There were some individual things, but we don't get the same pressure that Inter put us under, in the league.
"So it is good to get these matches so we see what we have to work on in defence as well. I saw things that we need to improve upon."
Deila revealed there could be changes for the game against Accies with John Guidetti (pictured) in line to start.
The Swedish striker, on loan from Manchester City, came off the bench against the Serie A side to grab an injury-time leveller with his first goal since November.
The Norwegian said: "He had a period where he was a little bit frustrated but he has stepped it up in the last few weeks."
