INTRODUCTION Hungarian football: nadir (WC1986; EC: 1972)
Present and the recent past: failures(2006: Malta 1-2; 2013: Netherlands 8-1)
Successes in the past: 1938, 1954 (Aranycsapat/The Gold team) Puskás; WC: II.place 1964: EC: III. place
(Mészöly-Bene-Albert) 1966: WC-quarterfinal Olympic Champions:

BASIC CONCEPT OF THE FORECASTING MODEL
Final outcome of a national match
1. Performance form of the players in their club teams
2. Basic qualities of the players
3. Other factors
Defending(%):- Succesful passes- Challenges won- Aerial challenges won - Succesful tackles
Attacking(%):- Succesful passes- Challenges won- Aerial challenges won - Succesful keypasses - Shots on goal- Succesful dribblings
- Fifa world ranking
- Last 5 comptetitivegames
- Home field

Balázs’s performance on the club match before the examined national match
Keypass% (here it’s missing)
We used this page to examine all the players of the 58 matches.

MULTIVARIATE STATISTICAL MODELSMultiple linear regression
difference between current form of attacker players and current form of opponent defender players (both team)
difference between current InStat index of attacker players and current InStat index of opponent defender players (both team)
difference between FIFA index of attacker players and opponent defender players
number of scored goals of attacker players in their previous club game
number of assists of attacker players in their previous club game
difference between the trends of their previous five matches of the two national teams
difference between the Fifa world rank score of the the two national teams
dummy variable of home field
