Lionel Messi apparently has some cracks in his armor. “The Flea” missed a first-half penalty kick Tuesday against Egypt in the Round of 16 of the World Cup, and the reigning champions, Argentina, entered halftime in a 1-0 hole. In the 21st minute, while down a goal, Argentina was awarded a penalty kick, but Egyptian goalkeeper Mostafa Shobeir read Messi like a book and leaped hard left to stop the shot dead in its tracks. Nicolás Tagliafico’s run in the 19th minute was challenged too aggressively by Haissem Hassan, and a penalty was quickly called in the box. This is Messi’s second missed penalty kick of the World Cup, as he missed the shot altogether during a 2-0 victory over Austria, where he also scored both goals in the win.
