Roma striker Pablo Osvaldo feels his side can aspire to great things following their 1-0 victory against Parma.The Argentina-born striker gave Roma their first Serie A win of the season with a second-half header, his second goal of the campaign.Roma were under intense pressure after enduring a disappointing start to the season which saw them crash out of the Europa League in the play-offs and secure just two points from their first three league fixtures. Pablo Osvaldo feels the team were worthy winners against Parma and will show their true colours once they have more time to integrate the ideas from new coach Luis Enrique.\"We deserved this victory because we have been doing great work and until today, luck was not on our side,\" he told Sky Sport Italia. \"We had to become mentally free. We believe in ourselves and that can be seen in the sacrifices we make on the pitch, but it is normal that it takes time to adapt to new things.\"Often in Italy, people do not give teams much time, but if we have time, we can do great things. This victory is important for us, the coach and the team-mates who stayed in Rome.\" The Stadio Olimpico outfit, who sit 11th three points off the top, welcome Atalanta on Saturday.
