The Welshman emerged as a scoring force in midfield last season, and carried on where he left off with his late intervention.
"It was very difficult. They came out and defended really well and were very tough to break down,'' Ramsey said. ``They lost their manager earlier in the week but you'd never have known that the way they played.''
Ramsey's goal in the FA Cup final in May ended Arsenal's nine-year trophy drought, and he provided the perfect launchpad to win the league title for the first time since 2004.
Performances, though, will have to improve if the trophy is to be taken off Manchester City. The winner was only scrambled in just after Arsenal gained a man advantage, with Jason Puncheon receiving a second yellow card in the 90th minute after receiving a second yellow card for a late tackle on Nacho Monreal.
Puncheon had set up Palace's opener in the 35th, whipping in a corner that Brede Hangeland was able to glance into the net with a header.
But Arsenal equalized on the stroke of halftime, also with a defender heading in from a set piece. Laurent Koscielny was unmarked when he met a free kick from offseason recruit Alexis Sanchez.
Although Arsenal paid $60 million for the Chile striker, this opening-day performance highlighted the need for more cutting edge up front, with goalkeeper Julian Speroni rarely tested.
Pulis' departure meant this fixture pitted the league's longest-serving manager against the most inexperienced, with Keith Millen in the Palace dugout less than 48 hours into his temporary reign.
"Who needs a manager'' Palace fans chanted in the early evening summer sun.
Pulis certainly proved his value to Palace last season, though, as he took control of a team facing relegation under Ian Holloway and won the manager of the year award as he kept them in the topflight.
