Nico Rosberg admitted his chances in the Spanish Grand Prix had been hampered by a DRS issue that made it difficult to try and get ahead of Mercedes team-mate Michael Schumacher.
The pair finished sixth and seventh in the race, with Schumacher taking the flag less than a second ahead of his fellow German after a heated battle on track that included the duo almost touching heading into turn one while fighting for position.
Rosberg's hopes of getting ahead of Schumacher were ultimately hampered by a problem with the DRS on his car, and with radio communication also failing early in the race, he admitted it hadn't been an easy race.
"It was a difficult race for me after I lost radio communication with the team early on which was tough, and my DRS was not working properly which made any overtaking almost impossible,” he said. “I had fun in the battle with Michael for P6, although I wasn't able to attack him fully and was therefore stuck behind him for most of the race. I'm now looking forward to my home Grand Prix in Monaco. I love the track and I'm sure we can be closer to the front there."
Schumacher meanwhile made up places with as strong start from tenth on the grid and from there on, the seven-time champion was happy with his run to sixth and his best finish of the season so far.
"We managed to make the most out of our possibilities today which is good news, especially for our guys who I am happy for,” he said. “I had a good start; going right through the middle was tight but fortunately it worked out.
“Then the race was about holding position from there. We can be happy with the result but other than that, it was just tricky with oversteer, tyre degradation and poor balance to deal with. Still we achieved what we could have, and I look forward to going to Monaco."
