Chelsea will have to pay £13m for Augsburg left-back Abdul Rahman Baba, according to the Daily Star website.
Chelsea are targeting the Ghana star, as Jose Mourinho looks to bolster his squad this summer, and his agent Sascha Empacher has revealed the Bundesliga club’s demands.
“Many big European clubs are interested in Baba, but they do not want to be named,” he said.
“Do Augsburg want €18-20m? Yes, that can be correct.”
