Manchester United must move to strengthen their defence heavily during the upcoming summer transfer window.

Former manager Jose Mourinho was desperate to add defensive reinforcements last summer but United tried and failed to land a number of key targets. Mourinho was left disappointed and United’s poor form on the pitch ultimately cost him his job. His replacement, Ole Gunnar Solskjaer, has performed admirably in the role and his chances of landing the job permanently has been greatly improved as a result of their performances.

Should the Norwegian legend be appointed, improving his defence must be a priority. Solskjaer has finally got the best from Paul Pogba as well as reinvigorating Marcus Rashford and Anthony Martial at the top of the field. Strengthening their back four would have United challenging for the title in no time.

One man the Red Devils should look to recruit is Lyon flyer – Ferland Mendy. Valued at £10.8m by Transfermarkt, the left-back has developed into a crucial player for his side since joining from Le Havre in the summer of 2017. Mendy is enjoying his finest season to date and has earned praise from fans and pundits alike due to his exceptional showings in Ligue 1.

The France international possesses blistering pace which allows him to keep up with the quickest of forwards as well as bomb forward to help out the attack. His biggest asset is his dribbling ability, averaging two successful dribbles per game this season, which helps him beat players with ease when bringing the ball out of defence. Mendy has also averaged an impressive 1.4 key passes per game this season which could mean even more goals for Rashford in the United attack (WhoScored).

Still improving and developing, this move should be a no brainer for Solskjaer.
