Four cheaper centre-back alternatives for Borussia Dortmund to consider

Jamil Siebert

The final option for a fourth string centre-back could be Jamil Siebert. Having just turned 22, he is still young and coming off a breakthrough campaign with Fortuna Düsseldorf. Following their failed promotion push, Siebert could still see himself rise up a division for the second consecutive season. Siebert dominated in the second-tier last season with just under 90% pass completion, while playing the ball forward continuously with nearly four progressive passes per 90. Siebert also put in a considerable amount of defending with over three tackles and interceptions per 90 as well. Like Frances, Siebert would be fairly cheap and an almost a zero-risk signing with a nominal fee.

Borussia Dortmund will need at least one high quality centre-back to replace Mats Hummels and potentially a second with Niklas Süle's future up in the air. But a fourth central defender will almost certainly be needed to cope with the expanded Champions League and next year's Club World Cup. The BVB bosses need to look at many targets this summer and find a player capable with the ball and also defensively adept. While Nico Schlotterbeck played almost every minute of this season, more rotation will likely needed in the coming campaign, which will begin just one month after the European Championship.
