The trio returned to club duties on Monday following a summer break and were being put through their paces once more during a morning session on the banks of Lake Geneva earlier today.
They were joined by Naby Keita and Xherdan Shaqiri, who were stepping up their returns from injury ahead of the Reds' fixture with Lyon on Wednesday, which you can watch live on LFCTV and LFCTV GO.
