You are doing wrong here. First you took a penalty were Mata indeed got a good shot, but the GK was lucky. Its also not very wise to show a miss by Luiz to prove he is not a good penalty taker, since I could put here lot of penalty misses by Lampard, including his pathetic miss at 2006 World Cup, and Mata's aside, his penalty at UCL final was the worst, it was in the middle of the goal and Neuer almost got it. That does not make Lampard a bad penalty taker. Hazard seems to be a good choice for penaltys, but you could use better arguments.
