Arsenal are hoping to secure a deal for 25 year old defender, Eric Bailly from Manchester United. Arsenal have been less than compact at the back, and Emery would like to improve the situation by signing the Ivorian.
Shkodran Mustafi has had a poor season, epitomised by the shambolic defending against Crystal Palace in the 2-3 defeat at the Emirates stadium.
Arsenal have conceded 46 goals, and with Rob Holding still unfit due to injury, Laurent Koscielny reaching the twilight of his career and Konstantinos Mavopanos still learning, defensive reinforcements seem in order for the Gunners.
With Bailly only playing 11 times so far this season and United likely to sign reinforcements in the defence in the summer, Bailly may be a player that could be sold.
Both United and Arsenal are currently sitting outside the top 4 in the Premier League as they look to battle there way into the Champions League places.
