some assistance please

[MJ98]

I am an American going to England in the middle of March, and will be going to Goodison March 22 to see the West Ham match. My father was from Liverpool, and that side of my family is still there
Some of my family will be attending the match with me, but i wont know how many (less than 10 surely) until that weekend, or maybe a little while before

Will I have trouble getting tickets on match day? I dont know if matches sell out beforehand, so maybe i should try to buy them online beforehand with a guess of how many i will need?
if it is sold out, are tickets sold on the street thru scalpers and the like?

thanks

Would advise buying before hand and picking them up on match day.

Even if you do get tickets on the day, you won't have the best of views.
