Willian’s Brazil team-mate Neymar may have left Barca for Paris Saint-Germain last year, but Willian said the LaLiga leaders were still hard to beat.
“I think Barcelona are Barcelona, with or without Neymar,” Willian said.
“Of course Neymar is a great player but they have Messi, they have [Andres] Iniesta, they have [Luis] Suarez.
“They have really good players so Barcelona is always Barcelona.”
Willian’s 62nd-minute strike was cancelled out by Lionel Messi as the teams played out a 1-1 draw at Stamford Bridge in the first leg of their Champions League last-16 tie.
