The Dutch coach praised the effort of his players in recent weeks after "eight games away from home, with long journeys, it's been really hard. It's a shame about the final two minutes of the Supercopa, but we're still in the Copa and we're getting better in the league."
On Francisco Trincao and Riqui Puig, who started against Rayo, Koeman said: "I think they both played well. Trincao above all created a lot of danger in the first half, there were various moments...
"And Riqui was good, above all playing through the lines... The pitch wasn't great for his game but he did well. We made the changes to freshen things up."
Koeman said the plan now is to take things "game by game. We will try to win all the games to move up the table and cut the gap on the leaders. We have the Champions League, the Copa and we want to keep going and show our mentality."
