Graham Potter admitted Chelsea’s Champions League last-16 triumph over Borussia Dortmund lifted a weight off his shoulders. The Blues won 2-0 at Stamford Bridge on Tuesday to overturn a 1-0 first-leg deficit and advance into the quarter-finals. Having beaten Leeds last weekend, the victory over Dortmund secured Chelsea’s first back-to-back wins since October and relieved the pressure on Potter after a poor run of results. “Has the weight been lifted off my shoulders? Yes, in some ways,” he said.
