Ray Parlour has urged Arsene Wenger to sign Mats Hummels, Sami Khedira and Morgan Schneiderlin to strengthen Arsenal's squad.
The Borussia Dortmund defender has been a transfer target for Manchester United, while Arsenal have also been reportedly interested in securing his services. Meanwhile, the Real Madrid midfielder has been on the radar of Chelsea, United, and also the Gunners.
Schneiderlin was set to leave Southampton earlier in the summer. However, the Saints were adamant in letting their star player leave and the Frenchman has been linked with a move to north London as both Arsenal and Tottenham are keen on securing his services.
The Gunners legend believes the defensive position is where Wenger should strengthen in order to finish the season in top four and also compete for silverware.
"Winston Reid has been mentioned, but I'm not sure he's the quality we need. Mats Hummels would be great, a world cup winner and a good player," Parlour said during a Q&A on Sportslobster.
"For midfield, I would go for Schneiderlin if you can get him. He's at a good age. Lots of players are linked. Khedira would have been great. Players that have played in big games won't be phased by anything. Schneiderlin hasn't, but I can see him improving."
Meanwhile, Lukas Podolski has failed to feature regularly for the Emirates club and the German international has been a target for several clubs across Europe. Parlour claims the forward is finding it difficult to fit into Arsenal's system and also blamed his work rate for lack of appearances.
"A lot of it's down to work rate. He's good to bring off the bench. We weren't chasing a goal so it wasn't the right game for him. Another problem is where do you play him? Giroud and Welbeck are ahead of him and you can't drop Sanchez to play him on the wing," the former Arsenal midfielder said.
"He's not a bad player but he doesn't really fit in the system. If Arsenal change and play two up top then he could do more of a job. The formation we play now doesn't really suit him," Parlour concluded.
