"It was a difficult game, but at the end of the day we won and that is the main thing," said Benitez.
"I think the game was a bit strange because we scored a goal and then they were attacking, and we could only play on the counter attack.
"We played open against a team who have pace and ability - this is always a problem.
"They needed to attack and had three strikers. They also had one or two players between the lines, so to control five players with pace and ability isn't always easy.
"We knew before the game that they have good players and we were not controlling the game or keeping the ball - the game was too open and they had too much space. They were always a threat.
"We were trying to play Torres in with the final pass too quickly sometimes, and that is something we have to analyse. But the main thing today was to win and qualify, so we are really pleased.
"Clearly we need to improve our possession - we need to keep the ball better and were giving it away too easily."
