Not actually American. Unless Di Marzio says so.
Lampard was quality technically, how else do you think he played at such a high level when his physical attributes had been criticised since he was a kid?He is not actually that bad as you have described. Yes, he is not as technically gifted as Buendia or Aouar. But from time to time, he did pull of some dribbling skills.
However, what let him down is his directness, his decision making, and his passing/through pass/one touch pass/one twos.
His passing and decision making was fine as well. After Mourinho went there Lampard had double digit assists in four of the next seasons, and 8 and 9 in the other two. Don't tell me this guy is ****:
