Roberto Martinez believes Everton will have to get stronger if they are to compete in Europe this season.
The Premier League side's 3-1 loss to Bundesliga new boys Paderborn means they ended their pre-season fixtures without a win.
However, Martinez believes the trip to Germany will prove a positive experience ahead of the Toffees' participation in the Europa League this term.
"We wanted to have a trial of what we will experience when we go away in Europe and it was exactly that," the Spaniard told Everton's official website.
"The game served its purpose and we know exactly what to expect now. We need to be strong and not give soft goals away."
Martinez went on to say he is eagerly anticipating the start of the new Premier League season, with his team travelling to newly promoted Leicester City on August 16.
"It's going to be a really good week now getting ready for Leicester, which is another challenge again," he added.
"We're looking forward to it and getting back to playing league football."
