it's not just his positioning and passing but his decision making, he senses danger and always manages to pick a safe option. in the above video there is a moment he could have headed to his left to his free defender i think it was but he sensed danger as the other team pressed forward and even though his player was free he opted to header forwards, very good decision making instead of putting his player under pressure.
Lucas is nowhere near as good, he wasn't even considered good enough for Brazil's national team at the world cup and even Ramires who isn't considered particularly good has played more international games than him.
Lucas's injury is to his ACL, players never make a full recovery from an ACL and usually get the same injury over and over again having to have the same operation 3 or 4 times. The knee joint and the shoulder joint are the two most complex in the body, if you injure either properly like ACL or Rotator Cuff then you never ever get back to 100%, you can strengthen it and let it heal, but it's never the same again.
I've hyper extended one knee playing football, ortho surgeon said i'm lucky im super flexible otherwise i would have torn my ACL, thank god it never happened because i know how bad they are, i also damaged my rotator cuff doing overhead presses, it has healed and been strengthened but i now take extra care when weight lifting because i can feel it's no longer the same.
Lucas will most likely be injury ridden for the rest of his life, especially when you take into account the amount of physical stress his knee will have to go through, very rarely after an ACL tear does the player never have issues again.
Lucas will play again for Liverpool, but he will be prone to injury, if he focuses on not damaging his knee then other muscles and joints will be put under pressure making them more injury prone.
Sorry but Lucas most likely will never be fully 100% ever again.
Lucas is Brazils best CDM, he was U20 captain and has been a regular for Brazil. he made the most tackles in any of the top 4 leagues in the whole of last season. Liverpool have missed Lucas more than season, than missing Stevie for 8 months, and that's a fact. We're a different team without Lucas.
Yes he didn't go to the last world cup, but he will be at the next one I'm sure of it. he's only 25.
Yes Lucas has injured his ACL, but you're stating that players never make a full recovery? Well that's just rubbish frankly. Van Nistelrooy made a full recovery after doing his ACL and went on to play for many years at Man U? Owen tore his ACL and made a full recovery (his injury problems are down to his hamstring injuries as a kid at Liverpool). Jamie Redknapp, Lothar Matthaus also have done their ACL's and both had long careers.
Also, players do make full recoveries from ACL injuries and they very rarely do the same injury again. It's very unlikely. There are three choices as to what to do once you tear your ACL:
1)You can repair it by using part of your hamstring, which generally takes around 9 months to heal.
2)You can take the middle part of your patella tendon and get that fixed into place, which generally takes 12 months.
3)You can take the ACL of a dead person who has given his body away to science and medicine and get it transplanted into your knee.
With the hamstring it takes less time as the hamstring heals quicker. The patella tendon takes more time as the patella has to heal from the damage you do taking the middle section of it away. However both are then STRONGER than a ligament. Although it can't send eletrical signals up and down the ligament to aid with balance (you have to teach your other muscles around the knee to do that for you - effectively learning to walk again), they are stronger to break and take many many hundreds more newton meter forces more than a ligament. So it's very unlikely for it to break again, or get the same injury. Especially in the first two examples as the grafts aren't going to be rejected as they are taken from your own body. The third one is pretty rare, though Richard Steadman does do it apparently.
I can also tell you it is absolutely possible to make a full return, like Lucas will. I can tell you that with 100% certainty because I ripped my ACL and cartilidge in May 2010. I was back playing again 6-7 months later (non contact 5-7 aside taken at a light pace) and a full recovery after 12 months. I'm back playing minimum three times a week. Although obviously not at the same intensity, it is possible.
You can't say he will never be 100% again, as he has a chance to be. The operation was successful and he's already working in rehab. If he can regain the form which he had for Liverpool over the last 18 months then he will be a monster again.
