Groningen and Sparta both have working supply into the box, while their protection after attacks remains uneven. Crosses, regains and second balls have opened their recent matches in different score situations. The first goal looks more likely to change the spaces than to establish lasting control.
Groningen can reach Willumsson through Thom van Bergen's delivery and aerial combinations, including Rente's corner flick at NEC. Sparta have their own connection through Babadi, whose service has found both Toornstra and Zonneveld. Those routes meet defences recently beaten by counters, free crossing receivers and runs behind.
Hernes was injured after entering Groningen's cup match, removing a midfield alternative. Sparta's Mito status remains conflicted, and my picture uses the attack already operating without him. Expected returns among the league defenders add experience, while the short recovery leaves little time for collective work.
An initially crowded centre can give way to wider spaces as the teams chase goals and recover second balls. Neither side has recently managed changing game states securely. That's why I'm backing a high-scoring Groningen–Sparta match.
