Everton boss Marco Silva believes he's discovered where they're struggling in games.
Silva thinks he has now pinpointed where his side are struggling in certain matches at least.
The manager told the Liverpool Echo: "Of course during the season we had some problems, I can tell you, with the type of football some teams play against us.
"It's something you are aware of, and it's something I want to improve as a manager.
"When teams play more closed against us, with more defensive organisation [the problems occurred]. I'm aware of the situation and it's up to me to find the right ways of achieving that."
