3) Laurent Koscielny/Kostas Manolas (Arsenal)
With Arsenal perhaps in need of a replacement for Per Mertesacker, the Gunners have been linked with a move to sign AS Roma centre-back Kostas Manolas. The talented Greek international caught Arsenal’s eye while he was at previous club Olympiacos, and he has impressed again in Italy, looking like the ideal player to come in and form a strong partnership with Koscielny at the back.
