Antonio Conte's Chelsea romped to last season's Premier League title with a system seldom used in England , incorporating three centre backs and two wing backs 

This type of back line has been emulated by Pep Guardiola and Ronald Koeman at Manchester City , Everton respectively as well as Arsene Wenger at Arsenal , with the former spending a staggering amount of money on full backs, outlining the importance of the role they now play at the top end of English football.

As with every successful philosophy there is a trickle down effect, and as the season wears on you will see more and more sides adopting the system.

This can be deployed either with an interchangeable front three with two deeper lying midfielders or a three man midfield and playing two through-the-middle forwards.

Mark Warburton with his rejuvenated Nottingham Forest side has dabbled with the 5-3-2 sporadically in the Championship campaign, and used it from the outset in the 3-2 win against Newcastle in the Carabao Cup last Wednesday night.

With Ben Osborn causing major issues in an untested left wing-back role, Forest were the superior of the sides until they reverted to a back four at half time when 2-1 up, after which they were very much under the cosh against a weakened Newcastle side and looked to be on the ropes after Rolando Aarons wonder strike levelled the scoring.

Seeing this, Reds boss Warburton opted to bring on Jack Hobbs and restore the three man central defence.

Forest regained the ascendancy, and with much of the game surpassing the midfield, Newcastle's extra man didn't count for much.

An extra time Tyler Walker header granted Forest a passage through to the third round, but there are perhaps long term benefits of the victory.

The ex-Brentford boss, who has favoured a 4-3-3 throughout his managerial career, may look to simulate the success of Antonio Conte last season, building league success on a back five.

The system is not quite in the EFL mainstream just yet, and Forest could be beneficiaries of this, showing thus far they have the personnel to do so.
