Former Arsenal captain Tony Adams believes Per Mertesacker has the ability to write his name into Gunners legend alongside Thomas Vermaelen.
Mertesacker moved to the Emirates Stadium from Werder Bremen in the summer and, by his own admission, took a while to adjust to the rigours of the English game.
He has, however, firmly established himself in Arsene Wenger's side, and has impressed with his composure at positioning at the heart of the Arsenal defender.
Adams has certainly liked what he has seen from the imposing German, and is now keen for him to blossom alongside Vermaelen, when the latter returns from injury.
And, with Laurent Koscielny also in the mix, Adams says Arsenal may have three centre-backs on their hands to match the finest in the club's illustrious history.
“I've seen Per Mertesacker a few times now, he interests me and I think he is a good player,” Adams told Arsenal.com.
“I think he is very intelligent and he knows how to play central defence.
“I'm really looking forward to seeing more of him because I don't think Thomas Vermaelen has actually played enough with him just yet.
"But they could be a fantastic central defensive partnership and would certainly excite me.
“It'd be like going back to the days of Adams, Bould, Keown maybe.”
