Everton boss Roberto Martinez is delighted with the defensive partnership of John Stones and Phil Jagielka.

In the 17 Premier League matches alongside each other this season, the Toffees have conceded only 14 goals.

"They complement each other really well and the most important reason is that they are phenomenal footballers," Martinez told evertontv.

"In Phil Jagielka, you have got a captain, a leader and someone who is probably enjoying the best football of his career.

"He has that chemistry and understanding with someone so talented like John Stones. It is a joy to see John developing and growing as a footballer. To see him doing it alongside Phil, it is a very natural partnership and it has been really effective for us.

"We have been delighted with that partnership and all the levels in their defensive duties."
