JURGEN KLOPP turned into Jurgen Crock after a freak collision put one of his stars in hospital – and left him facing a left-back crisis.<br /><br />Kostas Tsimikas suffered a broken collar bone when a touchline tangle with Bukayo Saka ten minutes before the break sent him crashing into the Liverpool boss.<br /><br />Both Klopp and the Reds defender hit the deck, and Tsimikas was left holding his shoulder in agony.<br /><br />He was immediately taken to hospital, where it was confirmed he had suffered a broken collar bone, leaving Liverpool with a huge injury headache.<br /><br />Andy Robertson is still out after shoulder surgery in October, and Tsimikas’ KO soured a thrilling match for Klopp.<br /><br />He admitted: “It was massively overshadowed by Kostas’ collarbone issue, and it is broken, so he is out for a long time.<br /><br />“I thought at first it was not a real problem because I had no pain. I would happily give my collar bone and Kostas would be fit again.<br /><br />“I was completely fine and I thought him, too, but I asked Kostas and he said 'No, it's broken.’ Of course, that’s not cool and you’re kind of involved.<br /><br />“I’m not even sure if I fell on him and these things should not happen. The other issues we will have to see, but it is hard for us to swallow with the Robbo situation.”<br /><br />Referee Chris Kavanagh penalized Saka for the foul, yet there was no intent in the incident and the Arsenal winger swiftly apologized after the top-of-the-table draw.<br /><br />Saka said: “I want to apologize to him. I didn't mean it of course. It was just a 50-50, I went shoulder to shoulder with him.<br /><br />“I didn't see him but he must have taken a bad fall. I didn't see that he went into Klopp either. I kept running because I didn't think it was a foul.”<br /><br />Centre-back Gabriel headed Arsenal in front after only three minutes, with Mo Salah leveling it just before the half-hour.<br /><br />It means the Gunners top the table at Christmas – yet Klopp felt Liverpool should have had a penalty when Martin Odegaard handled in the box.<br /><br />The Arsenal skipper escaped as it was ruled that he was using his arm to steady himself as he fell. Klopp didn’t blow a fuse but did feel hard done to.<br /><br />He added: “I’m pretty sure someone will tell me it’s not a handball but I don’t know how. I don’t say the ref can see it because I don’t know where he was.<br /><br />“But how can a guy in an office see that and not conclude that maybe, possibly it could be worth the referee having another look?”<br /><br />Gunners boss Mikel Arteta insisted it was the most high-octane clash he had seen in two decades – and delighted that he will sit down to Christmas dinner as a table topper.<br /><br />Arteta said: “It was an unbelievable game, one of the most intense I've witnessed in 20 years in this league.<br /><br />“I'm happy to be where we are. Tomorrow we will have a beautiful dinner with our families, then it’s back to work."<br /><br />Klopp also felt it was an honors-even showdown, and reckons it was proof that Liverpool has what it takes to mix it with the best in a title race again.
