Roberto Martinez has insisted that he is "one of the most flexible managers tactically" following Everton's third win in a row in the Premier League.

With Romelu Lukaku out injured, the Toffees played in a 4-1-4-1 formation instead of the 4-2-3-1 that they have favoured for the majority of this season to secure a 1-0 win over Southampton on Saturday.

The manager told the Liverpool Echo: "The people who say that I am tactically not flexible are people who do not follow my work. I have been innovative at every football club I have been at with my tactics, my shape and my approach.

"I am not someone who needs to defend myself but if you follow my work then I am probably one of the most flexible managers tactically that you could work with.

"In certain games we played with two strikers, on Saturday we had Aaron Lennon really high up the pitch and James McCarthy had freedom. We don't play the same way twice, but it is not for me to go openly and publicly and tell everyone what we have done."

Everton sit 11th in the Premier League table ahead of a trip to Martinez's former club, Swansea City, on Saturday.
