Football: Mancini bemoans treatment from rival manager

Roberto Mancinihad a touchline row with Aston Villa boss Paul Lambert during Citys 4-2 League Cup third round defeat at Eastlands on Tuesday in the latest of a long line of managerial disagreements involving the City chief.The Italian has rowed with Manchester United manager Sir Alex Ferguson, Evertons David Moyes, Stoke manager Tony Pulis and QPR boss Mark Hughes.His argument with Lambert came after he remonstrated with fourth official Martin Atkinson when Joe Bennett fouled Gareth Barry.And the former Inter Milan coach thinks that other managers treat him differently but can not explain why.I am tired of this manager because I didnt say anything to him, Mancini said. I asked the fourth official if it was a yellow card without moving my hands.Some managers go to bigger stadiums and they dont say anything. I am tired of this, very tired.I am tired of their behaviour and its better that some managers shut up because I didnt speak with this manager. I asked the fourth official if it was a yellow card and I thought the referee had left his yellow cards in the dressing room.Every time that I say something they complain. I didnt say anything but after when they go for example Old Trafford they never say anything.I dont know why. I am Italian but I dont know the reason. I didnt say anything to him, only with the fourth official.Mancinis team have only won twice in their seven matches, which has seen them concede 14 goals.The Premier League champions have also failed to win any of their last four matches and Mancini is sure about where his teams problems lie.We need to work with our defenders because they dont work well at this moment, he added.Its clear there are four competitions to go for, but this is the only competition we didnt win and because of this we wanted to stay in.We are missing this cup and we are disappointed with this.Were not playing well and our play is not quick. We want to have one more touch every time and its no good.Mancini also confirmed that Citys England midfielder Jack Rodwell, who had been due to start the match, had sustained a groin injury in the warm-up.City took the lead with Mario Balotellis first goal of the season but saw Gareth Barrys own-goal pull Villa level.When Aleksander Kolarov fired in a free-kick, Villa replied again with Gabriel Agbonlahors strike earning extra-time.Six minutes into the extra period Charles NZogbia scored Villas third goal before Agbhonlahor added the fourth.Villa manager Lambert has only seen his side win once in the Premier League since he took charge in the summer.But the former Norwich boss feels they are making significant improvements despite losing 4-1 at Southampton at the weekend.Its a massive result for us and we were excellent right from the off, he said.For 45 minutes we played well on Saturday (against Southampton) and you get games where you cant put your finger on what went wrong.It was a huge effort from us here and we didnt deserve to go a goal behind.We showed character to come back twice and go on and win the game and were delighted with the performance.
