John Carver has labelled Moussa Sissoko's reckless lunge on Lucas as 'indefensible' as the Newcastle boss refused to make excuses for his captain. The midfielder was sent off for two bookings in the 2-0 defeat at Liverpool Sunday night, but he could've seen a straight red after he caught Lucas on the ankle. The defeat was Newcastle's fifth in succession and left them with work still to do to ensure they do not get pulled into the relegation battle. Moussa Sissoko lunges in and makes a terrible tackle on Liverpool midfielder Lucas . The 25-year-old was sent off for a second bookable offence during Newcastle's defeat at Anfield . Carver admitted Sissoko could easily have been shown a straight red, pulling no punches. He said: 'The sending off, it could have been a straight red, I will be honest. I have said that to Moussa, I am quite straight and I won't defend anyone if it is indefensible.' Asked if Sissoko could be fined, Carver said: 'I am sure there will be some kind of disciplinary procedure. I said before the game we needed to keep 11 players.' Lucas goes down in pain after Sissoko's nasty challenge at Anfield on Monday night . Newcastle manager John Carver labelled Sissoko's tackle as 'indefensible' While Carver did not complain about that decision, he was angry that Ayoze Perez did not earn a penalty after apparently being felled by Dejan Lovren. He said: 'The game hinged on a huge decision. I don't want to be seen to be a moaner but it is fact we don't get big decisions for whatever reasons, it could be me. I have spoken to the referee, but it doesn't help me.' Carver did see reason for some optimism, feeling that his side's performance was much improved from their derby loss to Sunderland last time out. Sissoko is given his marching orders by referee Lee Mason after picking up two yellow cards . He said: 'I thought the first nine minutes we were very tentative, nervous after our performance against Sunderland. It was a bad goal to concede. 'After that we grew into the game. It is easy to crumble at Anfield but we didn't. One or two guys rolled their sleeves up. 'I think we got a response. We didn't get a result but I saw enough. 'There are lot of positives to take from the game. A lot of people expected us to get a hiding and I think we held our own for the majority of the game.'
