The first tip on this list comes from the Dutch Eredivisie where Heerenveen takes on AZ Alkmaar in the Europa League play-off first leg.
Heerenveen finished the regular season in eighth place, whilst AZ were fifth in the table.
When these two last met on 23rd April, AZ won the game 2-1 thanks to goals by Jesper Karlsson and Tijjani Reijnders after Heerenveen had taken a seventh-minute lead through Amin Sarr.
Since then, Heerenveen have drawn 3-3 with Camburr, as well as 2-1 and 3-1 victories over Vitesse and Go Ahead Eagles on either side of a heavy 5-0 defeat to Ajax.
On the other hand, AZ suffered a shock 3-1 defeat to RKC Waalwijk after drawing 2-2 with both Utrecht and Ajax after a 1-1 draw to Sparta Rotterdam.
