That's our only Lucas option imo, but he needs to cut out those marauding runs leading to nowhere in that case.
The decision to not sub Lucas in that Chelsea game worries me a bit. Klopp's explanation was that we didn't have any other option and people quickly presumed that it only affected Allen, but he could have subbed Lucas for Allen and moved Can to DM. Unless Klopp also doesn't rate Can in that DM role.
