Martin Skrtel had no doubts about signing his new Liverpool deal.
He believes the mood at Liverpool has been transformed since the arrival of Roy Hodgson in July.
"Lots of things have changed at the club this year with new players, a new manager and new medical staff. The spirit is very good and we showed that against Arsenal with a great performance. We can build on that and carry it on.
"We have quality in the dressing room and I know we will do better this year. A club like Liverpool deserves to win trophies and I will help them do that, hopefully this season.
"Everyone plays football to win trophies. Playing for Liverpool is a big motivation for everyone and we will do everything we can to win the Premier League. We have the highest targets - to win everything."
