Manchester United's need for a new defender this summer is startlingly apparent.
With stalwarts such as Patrice Evra and Rio Ferdinand entering the winters of their careers, along with the frequently injured Nemanja Vidic far from guaranteed to play an entire season, it's fair to say the champion's back line has seen better days.
And this is exemplified by the fact United's defensive record last season was the worst in 11 years.
In the first 19 games of the 2012-13 Premier League season, United conceded 28 goals, an average of 1.47 goals per match. The last time they suffered a worse defensive record was in the 2001-02 season, which saw the Red Devils finish third in the table.
And, after starting their campaign with a porous defensive record last season, United ended it by shipping five goals against West Brom in a sensational 5-5 draw—the sort of performance that might have led to Sir Alex Ferguson looking for the nearest available plug socket of which to attach his infamous hairdryer to, had his side not won the Premier League title four games prior.
And it was only the fact United won the title that has led many to forget how shambolic United's defending was at times last season.
Yes, there are starlets emerging through the ranks that could prove to be the green shoots of recovery.
Youngsters such as Phil Jones and Chris Smalling look promising, but a knee operation and broken metatarsal respectively wrecked each player's seasons last term, limiting them to a scattering of appearances.
Which is why United need to firm up their back line this season.
Here are the four defenders who could help achieve that.
