Premier League manager of the month?

There have been 4 games played in November/December before and after this year's world cup, so the nominees are assessed for the results in this period and not the games after the New Year.

Mikel Arteta (Arsenal)
Games: 4
Wins: 4
Draws: 0
Losses: 0 
Goals scored: 10 
Goals conceded: 3 

Arsenal have won all their matches in this period, when they beat Chelsea, Wolverhampton, Brighton and West Ham at New Year’s Eve.
Offensively, they have sprung and scored 10 goals in 4 games while conceding only 3 goals.
Arteta deserves to win the award this time as he is doing an excellent job.

Jürgen Klopp (Liverpool)
Games: 4
Wins: 4
Draws: 0
Losses: 0 
Goals scored: 10
Goals conceded: 4

Liverpool also got 4 wins straight in this period, but the game has not been as good as at Arsenal. They have still given away too many chances and the midfield does not have the dominance and power Liverpool are remembered for. They scored 10 goals and conceded 4 in the period.

Eddie Howe (Newcastle)
Games: 4
Wins: 3
Draws: 1
Losses: 0 
Goals scored: 8
Goals conceded: 1

Eddie Howe and Newcastle continue to impress and are currently number 3 in the Premier League. Their greatest strength is their defense where they have 10 clean sheets which is the most of all teams.
In this period, they conceded only 1 goal and scored 8 themselves.

Thomas Frank (Brentford) 
Games: 4
Wins: 2
Draws: 2
Losses: 0 
Goals scored: 8
Goals conceded: 5

Brentford are also in a good period and in this period, they will especially remember the 2-1 victory over Manchester City at the Etihad.
Brentford's fresh style of play and their counter-attacks have proven to hurt several teams and their flexibility in their play is difficult to contain.
Thomas Frank is doing an excellent job which has also earned him a new long-term deal with Brentford.
