For the most part, the 26-year-old was decent for Tottenham Hotspur. Alli scored 67 goals and registered 61 assists in 269 appearances for the club's first-team before joining Everton on a free transfer back in January.
However, the Englishman's form has been scratchy for a number of years, so it should come as no real shock that he has not been able to get going at Goodison Park.
Alli has not found the back of the net or secured an assist in six appearances for his new club.
It is important to note that Liverpool have not genuinely been linked with a move for Alli.
Anfield Watch Verdict
When you are surrounded by better players, you tend to lift your game. Therefore, Warnock is probably right, Alli could be a far better player at Anfield in comparison to Goodison Park.
Liverpool are streets ahead of Everton on the pitch. There is a reason why the Reds sit in second-place on the Premier League table and the Toffees are fighting relegation.
But, if we are being honest, Alli is not good enough to play for Jurgen Klopp's Liverpool right now. The aforementioned figures back up that particular argument.
