How to combine data frames with differing nr of rows and sort equally

dfa
              date league                  a                   b home draw away
1 2019-12-22 17:00     BL          Paderborn Eintracht Frankfurt 3.48 4.06 2.01
2 2019-12-22 14:30     BL Fortuna Düsseldorf        Unión Berlín 2.80 3.31 2.67

dfb
                    c                         d home1 draw1 away1
1      TSG Hoffenheim       Eintracht Frankfurt  2.37  3.60  2.75
2          Schalke 04  Borussia Mönchengladbach  2.40  3.50  2.75
3          RB Leipzig              Unión Berlín  1.25  6.00 10.00
4           Paderborn       Eintracht Frankfurt  3.40  4.00  2.00
5           Paderborn          Bayer Leverkusen  5.25  4.50  1.53
6               Mainz               SC Friburgo  2.30  3.30  3.10
7       Hertha Berlín          Bayern de Múnich 10.00  6.00  1.25
8  Fortuna Düsseldorf              Unión Berlín  2.75  3.25  2.62
9  Fortuna Düsseldorf             Werder Bremen  2.50  3.50  2.62
10            Colonia                Wolfsburgo  2.70  3.40  2.50
11          Augsburgo         Borussia Dortmund  5.00  4.33  1.57

I wish to combine dfa with dfb and get the below result.

data
              date                  a                   b home draw away                  c                   d home1 draw1 away1
1 2019-12-22 14:30 Fortuna Düsseldorf        Unión Berlín 2.80 3.31 2.67 Fortuna Düsseldorf        Unión Berlín  2.75  3.25  2.62
2 2019-12-22 17:00          Paderborn Eintracht Frankfurt 3.48 4.06 2.01          Paderborn Eintracht Frankfurt  3.40  4.00  2.00

I tried with this below but can't figure out how to arrange them with differing nr of rows. I'm looking for a solution that works no matter which df has more rows. Any input much appreciated.

myd <- merge(dfa, dfb, by = "row.names", all = TRUE)
