The Wales captain is pleased that the players have arrived at the Emirates and is looking forward to leading out his country in the Euro 2012 qualifier against Montenegro
The pair joined late on from Everton and Chelsea respectively, with the latter joining on a season-long loan.
The squad needed depth in midfield following the departures of Cesc Fabregas to Barcelona and Samir Nasri to Manchester City, whilst injuries and suspensions haven't helped either.
And after the 8-2 defeat by Manchester United, Ramsey is hopeful that the signings are just what the is needed to revitalise the club.
He told reporters: "They are both great players with plenty of Premier League experience.
"They are two players who have great qualities and hopefully they can bring something to the team.
"So far we have struggled with injuries so it is much better to have players in ready to play and to have that competition to keep you on top of your game."
Ramsey will lead out his country as captain in the Euro 2012 qualifier against Montenegro after a dismal first four games which see them sitting without a point at the bottom of the table.
He added: "The challenge now is to put things right and get switched on from the start. We need to start the game well," he said.
"Hopefully we can get that together in the next few games. We need to be harder on ourselves and start getting positive results."
