Virgil van Dijk has been one of the best defenders in the Premier League since arriving from Celtic.
Here are five reasons Chelsea should sign him:
Some criticism that has been levelled at Chelsea in recent weeks has been the goals that they have conceded from crosses and by headers.
Cesar Azpilicueta, while brilliant in other areas, does not have that natural height and against Tottenham Hotspur got caught out twice from balls over to his side, between he and Victor Moses.
At six foot four, van Dijk is superb in the air and would add to the height in both boxes which is something that can only benefit the Blues.
It looks like Chelsea are going to lose one of their greatest ever leaders in John Terry, who seems to be leaving the club at the end of the season.
There is some debate over who should take over the captain’s armband, with Gary Cahill and David Luiz the most likely candidates.
But van Dijk has also been captain at Southampton, and he has shown that he can be a top leader for them, and the more leaders Chelsea can get into their ranks the better.
Chelsea have been linked with some top players, but some don’t necessarily have the European experience that van Dijk possesses.
Having played Champions League football with Celtic, in the Europa League with Southampton and also caps for the Netherlands under his belt, at 25 van Dijk already has a wealth of experience.
With a likely defence of the Premier League and the Champions League to contest for, players like van Dijk can be an essential part of getting others through the difficult periods.
Gary Cahill has scored six goals for Chelsea so far this season, a pretty impressive tally from a centre-back, while David Luiz also scored his clever free-kick at Liverpool.
That is another attribute that van Dijk offers, with the ability to really go and attack the ball in the opposition’s box from corners and set-pieces with four so far.
A player like that adding in some crucial goals can definitely help get teams over the line and add an extra dimension to Chelsea’s play.
Bolstering the squad
With Champions League football next season, Chelsea are not going to have just bolster their squad, but they are going to have to do it with real quality.
There is no point just getting people in that are merely squad players, they need to be able to step into the starting XI when required and van Dijk is certainly someone that can do that.
He will be attracted by the opportunity of playing for the Premier League champions, if they go on to clinch it, but may have to make do with being a rotated player.
That’s unless he can prove to Antonio Conte that he deserves that starting spot, and with the ability he has shown that could be the case.
