The resumption of football in Europe's top five leagues still appears some way off due to the coronavirus pandemic, leaving players with plenty of time to analyse their performances this season.

Using Opta data, we have already examined some of the worst attacking and passing numbers from 2019-20, so now it's the turn of the defence.

We have analysed nine metrics for defenders to have featured in at least 10 league games this season, thereby giving us a good summary of those whose defending could use some improvement.

The metrics include success rates in duels, tackling and aerial challenges, errors leading to shots and goals and how many times a player has been dribbled past by an opponent.

As always when it comes to data, context is key. For success rates in duels, tackling and aerial challenges we have only included players who have completed 20 actions in each category, which accounts to two per game.

The below therefore provides a good indication on where improvement is needed, and there are a few surprising names…
