Arsene Wenger needs a little more steel in the centre of the park, with Granit Xhaka needing some real competition as Mohamed Elneny and Francis Coquelin fail to adequately put pressure on the Swiss star. Steven Nzonzi is man who has been heavily linked with the club and also has Premier League experience. Meanwhile, an aging and injury-prone central defensive unit is in dire need of a patch up, especially as Per Mertesacker eases into retirement.
The Cherries have just about enough in their forward line to get them through, but could do with a better shield in front of their back four.
