Hal Robson-Kanu felt Albion did more than enough to win the game at The Valley on Saturday.
The Baggies twice took the lead but were pegged back both times as Charlton held Slaven’s side to a 2-2 draw in London.
And the striker, who scored his seventh league goal of the campaign early in the second half, admitted his team-mates were left frustrated by the result.
He said: “It was a tough game.
“They were very physical throughout.
“We’re really disappointed to have drawn the game having gone ahead twice. We’re also disappointed with the goals that we’ve conceded.
“In terms of clear opportunities, I think we limited them and had a few ourselves.
“We feel we’ve got enough quality to get three points from games so it’s really frustrating.
“We had plenty of shots in the game but at the end of the day it’s just a point.
“On another note, it’s another point on the board and we’ll be fully focused on getting back to winning ways against Stoke.”
