"We controlled it pretty well, their only opportunity was with set pieces, the rest we defended really well," the Liverpool boss told Sky Sports News at full time.
"The whole game was a plot on the goalkeeper, everyone loves it in this country, but it makes life difficult for the goalie.
"It was a difficult game as the pitch got drier and drier. West Brom decided not to water the pitch at half time and that makes it difficult.
"It makes a massive difference. A team like West Brom do not need a wet pitch, they can do it next year playing on a dry pitch in the Championship."
Liverpool remain third in the table following the draw, three points ahead of fourth-placed Tottenham Hotspur.
