Oliver Glasner said Crystal Palace will work on finding solutions against strong defensive teams, after the Eagles were beaten by Everton following a cruel late twist at Selhurst Park.
Everton moved level on points with the Eagles after a late goal from Carlos Alcaraz secured the Toffees the win, after Palace had fought back level at the start of the second half through Jean Philippe Mateta's 11th goal of the season.
"It was a very disappointing result, very frustrating," Glasner told PalaceTV. "It was a little bit similar to the Brentford game. I think we had two or three good chances in the first half, we didn't take them - I spoke before about efficiency.
"The direction was good, we had the momentum. But also to be honest Everton did well. Our distances were too big (when pressing) because we were a little bit threatened by the long balls.
"They got into our final third. They got their set-plays, that they wanted and in one of these situations they scored the decisive goal. But this (set-pieces) is one of their strengths. They are very physical and in this situation we couldn't defend it.
"What I have to do, together with my staff, is to find better solutions against a team that defends also with a back five to create more moments, more chances.
"This is what we will work on, because the character of the team is amazing."
Despite the defeat, Glasner said now is not the time to panic and backed his side to respond with a positive display away at Fulham next weekend.
"Now we stay calm. Today everybody goes home disappointed and it's good like this. But then we will start preparing for this game at Fulham.
"It's good, we have one more training week for players coming back from injuries.
"Of course, it's good for Adam Wharton, it's good for Eze, it's good for Eddie Nketiah. And then we will go there, well prepared in the best way and give our best and try to win."
