This was probably a glimpse into what Mauricio Pochettino's Chelsea will look like when the Premier League starts. We're just over a week away, after all. The clock is ticking as players look to earn their place in Pochettino's go-to XI.
Well, one young star made his case. Levi Colwill, fresh off a new contract, was the standout in a 1-1 draw with Borussia Dortmund on Wednesday as he anchored the Chelsea defence alongside the veteran Thiago Silva. The young star clearly features in Chelsea's future plans, but it's performances like this that will see him become a key player in the present.
On the opposite end of the spectrum was Christopher Nkunku, whose status for the Blues' Premier League opener against Liverpool will be in doubt after the ex-RB Leipzig star suffered an apparent knee injury.
Wednesday night's clash was, largely, a pretty tepid affair, one decided by two second-half goals. Marius Wolff got Dortmund's in the 80th minute, finishing off a move after Chelsea failed to properly clear a set-piece. That, though, was answered by young Maston Burstow, who got a goal of his own in the 89th minute to seal the draw.
