The Gunners decided to push through a last-gasp deal to bring Monreal over from Malaga after first-choice left-back Gibbs hobbled off in Wednesday night's Premier League 2-2 draw against Liverpool at Emirates Stadium with a thigh problem.
Arsenal manager Arsene Wenger denied that Monreal's signing was a panic buy and expressed his belief that the Spanish international would be a success with the Gunners.
"We believe he [Monreal] can integrate our style of play and adapt very quickly to that," said Wenger.
"He has the characteristics to play our game because he is very mobile, has a good left foot and is very good in combination play. It is of course vital in our style of play."

Wenger will however be wary of throwing Monreal straight into the thick of the action when Arsenal come up a notoriously physical Stoke side.
But the French tactician insisted that his players would be up for the fight despite having faced some difficulties against Tony Pulis' men in the past.
Wenger added: "I don't believe that my players miss strength of character, they have plenty of character.
"They want to play in a bit more spontaneous way at home. We feel we have a bit of inhibition.
"We have to get rid of that and I think we have the strength of character needed to do it."
Meanwhile, Chelsea interim manager Rafael Benitez has remained calm despite coming under intense criticism going into their clash with struggling Newcastle at St James Park.
With Chelsea 13 points behind leaders Manchester United and six adrift of second-spotted Manchester City, Benitez has already conceded defeat in the title race, but he has expressed his belief that a top-four place and Champions League qualification would be possible.
"At the moment I am confident we can do it," Benitez said. "We're in the top three at the moment, doing well.
"I have confidence that we have enough quality and, with the players coming back, we'll have enough options to manage the games, win more games in a row and be in the top four."
In the late kick-off, Manchester United will hope to continue their recent good run of form at Craven Cottage against a Fulham side they thrashed 4-1 in the FA Cup at Old Trafford last weekend.
However, Red Devils striker Wayne Rooney has warned his side to expect a much tougher test this time round.
"The cup game was quite comfortable," said Rooney. "But at home, Fulham are a different team.
"They have got players who can take the ball between the lines because the pitch is not as big and then they can create chances.
"They are down near the bottom so they will be fighting to get one or three points."
Elsewhere, West Ham will go up against high-flying Swansea, Aston Villa will hope to stop the rot when they take on David Moyes' Everton, Reading will look to build on their incredible 2-2 draw against Chelsea in midweek when they clash with Sunderland, and relegation battlers Wigan Athletic and Southampton go head to head at the DW Stadium.
In Saturday's early kick-off, Adel Taarabt starred for QPR but failed when it mattered the most, failing to convert a penalty as they were held to a 0-0 draw by Norwich.
