Adrian Clarke looks at tactical trends of the 2019/20 season so far.
Tried and trusted
Only one of the 20 Premier League managers in charge on the opening day of the season has used the same starting formation in every match.
For that reason, they should be regarded as the most tactically stable side in English football's top flight.
Pearson has opted for a 4-2-3-1 during his 13 matches, as has Arteta across 10 encounters, using the most popular system among Premier League teams this season.
Least formation variations 2019/20
|One formation||Two formations|
|Chris Wilder||Daniel Farke|
|Nigel Pearson||Jurgen Klopp|
|Mikel Arteta||Sean Dyche|
Having used four different shapes in 2018/19, they have favoured two approaches across the current campaign.
Despite being embroiled in a relegation battle, Norwich City have strayed from 4-2-3-1 in all but two of their matches.
Daniel Farke is not the tinkering type.
Fewer changes by Ole
Compared to his first campaign in charge, Ole Gunnar Solskjaer has displayed far more tactical acumen this time around.
In 21 matches in charge of Manchester United last season, the Norwegian used nine different starting formations.
That figure has dropped to four in 2019/20, with 23 of the 29 fixtures featuring a straightforward 4-2-3-1.
For certain matches, Solskjaer has cleverly used the element of surprise, switching to a back three or opting for two strikers.
Changing shapes 2019/20
He is renowned for adopting fluid tactical strategies and will regularly alter the Seagulls' system during the course of 90 minutes.
However, in recent months, the Southampton manager has settled on using a 4-4-2.
West Ham United have begun matches in seven differing formations across only 10 fixtures under Moyes.
Mourinho, who has been hit by a series of injuries at Tottenham Hotspur, has also used seven shapes over the course of 17 matches.
Earlier on in their managerial careers, it was not common for either to alter their tactical line-ups.
But until this point neither man has stumbled upon a formula with which they are happy.
