It's no secret that Lampard wants to play every game. I like that he doesn't feel happy sitting on the bench, as no player should, but I get the feeling that he's second guessing The Boas.
Lampard and Mata had a discussion about who should take the penalty against City. The Boas said after the game that Mata was supposed to take it, but Lampard insisted on taking it himself. Some have said that Mata was only supposed to take it if Lampard wasn't on the pitch, but if that were the case, why would Mata and Lampard argue over who's gonna take it? Why would Lampard have to convince Mata to let him take it? It seems to me that Lampard put his personal need for glory and redemption ahead of the manager's orders. He almost did it in a way that said "See? You were wrong to drop me."
After the game, Lampard was quoted as saying the following: “I want to play, simple as that,” Lampard said. “I’m as fit as I’ve ever been. I’ve been in a good run of form and now I’ve not been playing. I haven’t spoken [to manager Andre Villas-Boas] so I don’t know why, simple as that.”
In all likely hood, a journalist asked him specifically about being dropped, but did he really have to add those last two sentences? It implies that he thinks the manager has been wrong to drop him because he's been superb (which is a bit of a stretch, in all honesty). This second guessing from Frank only strengthens the belief that the old guard have too much power in the dressing room. He should be respecting The Boas' decisions, like any good professional would do.
