The Reds' replacements in games have now scored 10 goals so far this season, which are evenly split between the Europa League and the Premier League.
The latest of these substitute strikes came from Fred, when the Brazilian midfielder came on to score against Nottingham Forest in Tuesday night's 3-0 win.
Ten Hag certainly seems to have taken full advantage of the Premier League rule change which allows managers to bring on fibve substitutes.
Speaking in his press conference to preview this weekend's game away to Wolverhampton Wanderers, Erik expressed his pride at the way players who are not named in his starting line-up can still influence the proceedings.
