6 Luciano Emilio DC 29 20 2007
As you can see, no player has ever registered at least 20 goals more than once. When Luciano Emilio did it last season, he was the first to do so in five years. This is Donovan's best goal-scoring year by far with 16 goals in just 18 games played. Can he make it to 20? That's a very interesting question.
Because MLS does not break for international dates, Donovan will likely miss at least two of the Galaxy's remaining eight games while on World Cup qualifying duty. The US plays Cuba on 9/6 and Trinidad and Tobago on 9/10, meaning Donovan will miss the 9/6 game against Salt Lake. The US plays the return legs of those fixtures 10/11 and 10/15, which means he'll likely miss the 10/12 game against Colorado. Factoring in fatigue and injuries from these games, he could also miss 10/18 against Houston and 9/13 against Kansas City.
If he keeps scoring at this rate, he'll finish with 20 goals if he plays at least five more games. Whether he plays that many remains to be seen. If he doesn't, it's yet another in a long line of arguments against MLS playing on FIFA dates.
