The Reds have been quiet in the transfer market, but the midfielder says the team is "bigger and better than last season".
Georginio Wijnaldum has heralded the strength of Liverpool's squad and does not believe their quiet transfer window should be assessed yet.
The Reds brought in key figures such as Alisson and Fabinho ahead of last season, with Virgil van Dijk joining in the previous window, but they have been quiet this time around.
Liverpool, who finished second in the Premier League but won the Champions League, have only brought in teenagers Sepp van den Berg and Harvey Elliott so far.
