RANGERS' Richard Foster believes there is sure to be more controversy when the Old Firm clubs meet again in the Co-operative Insurance Cup final at Hampden on March 20 and in their final Clydesdale Bank Premier League game of the season.
In their fifth meeting of the season last night, the Ibrox side were beaten 1-0 by Celtic in an ill-tempered and chaotic Scottish Cup fifth-round replay at Parkhead in which the visitors had three players red-carded.
Light Blues midfielder Steven Whittaker was sent off by referee Calum Murray in the 35th minute after picking up his second booking for a foul on Emilio Izaguirre.
After a bust-up as the two sets of players went up the tunnel at the interval, Hoops right-back Mark Wilson scored what proved to be the winner just after the break.
There was mayhem in the final moments as Rangers defender Madjid Bougherra was sent off in injury time after picking up his second yellow card and after the final whistle, as Celtic manager Neil Lennon and Rangers assistant Ally McCoist had to be pulled apart, the unruly El-Hadji Diouf, booked earlier, was booked again and red-carded for approaching Murray.
However, Gers winger Foster believes it was all "part and parcel" of the Old Firm fixture.
He said: "It is a Rangers versus Celtic game at Parkhead in the Scottish Cup so it would have been very difficult to go in with a calm head.
"For a neutral it would have been a great game to watch.
"From our point of view the result didn't go for us so I am disappointed.
"Right from the start both sets of players were up for the game and sometimes things happen in games, they boil over and I think that is just the Old Firm game.
"It's part and parcel of the Old Firm, the two biggest teams in Scotland.
"We will be looking to win the next two games against Celtic and I can't see them being quiet affairs."
