Sparta have conceded in 9 of 9, Ajax have won 4 in a row away: a goal fest at Het Kasteel?

Sparta have conceded in all 9 games this season and at least 2 in each of their last 7; at home they concede 2.40 per game over 5 games and have never scored first. Opposite them Ajax have won their last 4 away games (4.00 scored and 0.75 conceded per game away), are unbeaten in their last 5 and won all 5 of those by at least 2 goals. However, the opponents in those last five (Fortuna, Willem II, Excelsior, NEC, Groningen) are mid and lower-table sides; the only serious test was a 1-3 loss to PSV. Sparta beat Willem II (18th) 3-2 to win from behind for the first time; Zonneveld has scored 6 of the team's 16 goals (38%). Ajax are without Dolberg (2 goals), Caio Henrique, Gaaei, Edvardsen and Adingra, with Blind and Berghuis back in the group but uncertain to play; Sparta are only without Mito. Ajax's goals are spread out: Brandt has 6 of 27 (22%), Arokodare 4, and 17-year-old Mokio has 3 (all away). In the head-to-head Sparta have never beaten Ajax (14 games, 0 wins, 3 draws).
