Real Madrid maintained their title chase for a long time, but the clasico defeat left them reeling...
Los Merengues slumped to a fourth consecutive defeat on Sunday when they were beaten by Real Mallorca and the run of bad form began when they were hit for six by their arch rivals earlier this month.
With a trip to Osasuna to come, Parejo hopes that Madrid can end the campaign on a high note by recording a win that would send their hosts in the Reyno de Navarra down.
"Our morale dropped after the match against Barcelona. We practically lost the title, which naturally makes your motivation change," he told the club's official website.
"I think these games are hard to play, but the team's intention has always been to take three points, and it will be so again against Osasuna. It's our last game and we want to win.
Parejo returned to Madrid in January after cutting short a loan spell at Queens Park Rangers and he hopes he will have a chance next season to prove himself and not be sold in the predicted summer clear-out.
"It's a complicated situation, but I think we have to distance ourselves from everything that is being said and take things slowly. Whatever has to happen will happen," he continued.
"We simply have to play at our highest level and make good use of the playing time we are given."
