Arsenal continue to be on the lookout for new additions to the club in the 2012-2013, while they also appear intent on shedding some players who may have over-stayed their welcome.

According to Daily Mirror, Arsene Wenger assistant Boro Primorac has been scouting midfielder Riccardo Montolivo. The 27-year-old Italian has been a mainstay with Fiorentina for over six seasons, but his contract expires at the end of the season. The Gunners had shown interest in Montolivo last summer, and the versatile star might be an ideal reserve for Wenger.

Wenger may also be interested in adding Joel Campbell to the first squad. The Costa Rican forward is on loan at Lorient, after the Gunners added him for a fee of £900,000. Campbell, 19, has reportedly been impressive with the French club, and has scored against Wales and Spain in international competition.

While Wenger has shown active interest in adding players, there appears to be a strong interest in shedding players for lack of production, as well as for payroll concerns.

According to ESPN, Arsenal's wage bill has increased by £20 million. Andrey Arshavin, who is on loan at Zenit Saint Petersburg, is expected to be permanently moved. There have also been discussions of Nicklas Bendtner (on loan with Sunderland) leaving the Premier League, as well as Denilson and Carlos Vela, who are also on loan. Arsenal are in talks with Real Zaragoza about selling Vela  for £3 million, according to Metro.

Sebastien Squillaci and goalkeeper Manuel Almunia are expected to leave the club next season, as well.

With the probable addition of Lukas Podolski from Koln, Arsenal are expected to transfer struggling striker Marouane Chamakh. The 28-year-old Moroccan had been linked to numerous French and Italian clubs for months.

According to Daily Mirror, Paris Saint-Germain are interested in Chamakh, with a valuation of £6 million. Bordeaux, Chamakh's former club, and Fiorentina, are also linked to Chamakh.

The Gunners may not want to tinker too much with their current roster. Wenger's squad have made an excellent turnaround after a poor start to the season.

Arsenal have won seven-straight matches heading into a clash with Queens Park Rangers at Loftus Road Stadium on Saturday.
