The behaviour of Chelsea ’ s players as they surrounded Bjorn Kuipers was nothing short of disgraceful , but it ’ s a sign of the way the modern game is going . Blue shirts swarmed around the Dutch referee and the pressure put on him by Jose Mourinho ’ s men certainly played a part in the harsh dismissal of Zlatan Ibrahimovic for his challenge on Oscar , after replays suggested the PSG man pulled out . Chelsea are not the only team to harrass officials on a regular basis and it ’ s time we introduced a rule to put an end to it . Zlatan Ibrahimovic ( second right ) was sent off for a challenge in the first half on Chelsea 's Oscar . Chelsea 's players immediately surrounded referee Bjorn Kuipers to remonstrate with him . Referee Kuipers ( right ) swiftly showed Ibrahimovic a red card for the challenge on Oscar . There should only be one player from each side allowed to approach the referee and that is the captain . This is the only way to combat it . Chelsea were eliminated from the Champions League on away goals as they drew 2-2 with PSG , the tie finishing 3-3 on aggregate .
