Chelsea are reportedly considering a double swoop for Everton defence duo John Stones and Seamus Coleman this summer.
One of the main reasons behind the Blues' success in the Premier League this season has been their defensive solidarity, with them only conceding 27 goals (the fewest in the league) so far.
Captain John Terry, who seems to have been revived after Jose Mourinho's return in 2013, has been excellent at the heart of Chelsea's defensive this season along with Gary Cahill.
Fullbacks Cesar Azpilicueta and Branislav Ivanovic have also been very impressive this season, with the duo contributing in both attack as well as defence.
However, Chelsea's backline have been ageing, with Terry and Ivanovic being 34 and 31 years of age respectively, and the Blues are reportedly looking to get some younger defenders for the future.
And according to the Daily Mail, the West London club are reportedly interested in Everton duo Stones and Coleman.
Stones, 20, who completed a £3 million move from Barnsley in the summer 2013, has managed to quickly mature into a promising centre-back, with many tipping him to be a world-class player in the future.
The youngster has profited by playing alongside Phil Jagielka in the central back position and has shown great potential in reading the game and working the ball out of the defence.
He was especially very impressive during his side's 3-0 win over Manchester United last month where he netted his first goal in Toffee colours. His ability to play in the right-back position is also an added advantage for any side.
As a result, Chelsea boss Jose Mourinho reportedly sees him as someone who will be able to play alongside Kurt Zouma for the Blues at the heart of the defence in the future.
Everton boss Roberto Martinez would certainly be very reluctant to let the 20-year-old leave Goodison Park, but he may be tempted to consider if Chelsea come up with a very good offer.
Apart from the youngster, the Blues are also reportedly interested in Coleman, who has been very impressive for the Toffees since the last season, doing well in defence as well as scoring and assisting several important goals for the Toffees.
