Premier League side Chelsea have made an improved offer of nearly 22 million euros (£18.8m, US$28.7m) for Bayer Leverkusen\'s Germany star Andre Schuerrle, according to a media report here. Having made an initial bid of 20 million euros for the 22-year-old, Chelsea have raised their offer with Belgium midfielder Kevin de Bruyne reported to be part of the deal and he could join Leverkusen on a one-year loan spell. Duesseldorf-based newspaper the Rheinischen Post say Borussia Dortmund have also bid 17 million euros (US$22.2m) for de Bruyne, who is currently on loan at Werder Bremen and impressed in Saturday\'s 2-2 draw at Fortuna Duesseldorf. Earlier this month, Leverkusen\'s director of sport Rudi Voeller revealed Leverkusen were considering Chelsea\'s initial bid. From: AFP
