Gary Hooper believes a solid defence can help Celtic build on the point earned in their Champions League Group G opener against Benfica.
The Scottish champions were without Georgios Samaras, Anthony Stokes, Beram Kayal and Joe Ledley, while Hooper had to start on the bench after picking up a knock in the defeat at St Johnstone at the weekend, before replacing Emilio Izaguirre after the break.
Manager Neil Lennon admitted his side lacked a cutting edge but was pleased with their defensive diligence in the goalless draw against the Portuguese.
Ahead of the visit of Dundee in the Scottish Premier League on Saturday, Hooper declared himself similarly impressed with the Celtic rearguard who have kept a clean sheet in four out of five European ties this season.
He said: "I thought we dealt with Benfica really well considering they are a big team.
"We defended well and if we do that more and try to pick it up in the final third then I think we have a good chance of doing well in the rest of the games."
Thomas Rogne, who came on as a second-half substitute for Mikael Lustig, was pleased enough with Celtic's first group game in four years.
"When you don't win it's important not to lose," said the Norwegian defender.
"I think it was a good performance. We would maybe have liked to test their goalkeeper more but defensively we done well and one point is a lot more than nothing so we should be happy with the performance. It was a good start for us."
