Under Clarke, West Brom have predominantly deployed a now standard 4-2-3-1 formation, a setup that Clarke's former mentor Mourinho has utilized for most of his career.
New signing Claudio Yacob plays the holding role in midfield, while the more physically gifted Youssuf Mulumbu operates in the box-to-box role alongside him.
Clarke has tended to rotate his three attacking midfielders, with forward Peter Odemwingie often dropping back to allow Shane Long to play in the lone striker role.
With the speed and technique of both Long and Odemwingie at his disposal, he has the Baggies playing deep, counter-attacking football with quick passing and very little use of the flanks.
A good example of this is highlighted in the above diagram, which shows just how swiftly West Brom were able to attack on the break at one stage in their opening weekend win over Liverpool at the Hawthorns.
With the Baggies having seized possession thanks to a misplaced Steven Gerrard pass, James Morrison's touch and through pass to a clear Shane Long swiftly succeeded in splitting the Reds' defence in half, subsequently forcing Daniel Agger into a red-card challenge and a penalty for the visitors.
Though it must be said that when 6'3" striker Romelu Lukaku is on the pitch, the team often becomes far less narrow, allowing balls to be pumped into the aerially dominant Belgian from the wings.
Of all the teams in the Premier League, West Brom have had the third-fewest possessions, with an average of only 43 percent per game.
They are also among the bottom six teams in pass completion percentage and pass attempts per game.
But acknowledging these less than impressive numbers, it must be said that it has not been an attractive style of football that has caught the eye, but rather West Brom's ability to grind out wins with an uncanny effectiveness.
