Arsenal manager Arsene Wenger says loanee Yossi Benayoun can make an impression at the Emirates Stadium.
The Israeli, who moved from Chelsea until the end of the season on deadline day of the transfer window, is yet to make a league start for his new club.
Benayoun has been restricted to staring roles in the Carling Cup and from the bench in the Barclays Premier League, but Wenger says the winger can step in ably when called upon.
"He is doing well at the moment," he said.
"The season is so long that he will play his part and I am convinced that he will be an important player for us.
"His experience can make a big difference at some stage."
The 31-year-old was one of five new signings made late on in the transfer window, with Mikel Arteta, Per Mertesacker, Park Chu-Young and Andre Santos joining the Gunners' ranks.
Wenger says when the new players joined the club, the mindset completely changed.
"I am adamant that the players we brought in during the summer are top quality," Wenger added.
"They are also top quality men who have brought something to the dressing room — that is vital.
"They all have ambition and you could see that straight away after two or three days when the whole dynamic changed."
