Celtic reduced to nine men in Champions League defeat to Feyenoord
Celtic had Gustaf Lagerbielke and Odin Thiago Holm sent off within five minutes of each other as they opened their Champions League campaign with a 2-0 defeat by Feyenoord in Rotterdam.
Calvin Stengs gave Feyenoord the lead in first-half stoppage-time when his 30-yard free-kick evaded a poor attempt at a defensive wall.
Joe Hart saved a penalty after Lagerbielke received a second yellow card and substitute Holm soon got a straight red card in the 68th minute.
Alireza Jahanbakhsh got the home sides second goal.
Centre-back Lagerbielke was one of two summer signings in the Celtic starting line-up with Nat Phillips ruled out by an ankle injury. The other, winger Luis Palma, made his first start for the club.
There was a lively atmosphere inside De Kuip for the first meeting between the teams since Feyenoords 1970 European Cup final triumph and the first Champions League game in the stadium for six seasons.
Celtic took the edge off the atmosphere with a positive start and Reo Hatate got the first shot on target after the Hoops won the ball high up the park, but his effort lacked power.
