Baines admits there was a lot frustration after their late, late defeat at Chelsea on Saturday.
He told evertontv: "[The Spurs game was] similar to this in that we pretty much dominated. We've been to all of the big grounds and acquitted ourselves really well - we've been the better side more often than not.
"That's a positive but we've got to get more clinical in the final third.
"We need to add more goals to our game because ultimately that's what it's about if you want to win matches."
