Former Arsenal star says Tottenham have done 'ok', and predicts they will earn a draw with Manchester City.
The former Arsenal midfielder explained that he felt the Argentine had been a little fortunate to unearth Harry Kane, who has netted 30 goals in all competitions.
Spurs are currently in sixth place in the league, on course to finish in the same position as they did in 2013/14.
He said: "Mauricio Pochettino, on the other hand, has done OK at Spurs so far. He fell across the team slightly, but has brought Kane in regularly, and introduced Ryan Mason into midfield.
"But they need a few players, a few more of his own players to make them into the team he wants."
Merson went onto predict Spurs would draw 2-2 with Manchester City, a result which really would be a huge improvement against a side who season, under Manuel Pellegrini hammered them 6-0.
This may also tell it's own tale about City's backward step this season, falling back from winning the title to being 13 points behind leaders Chelsea.
Merson's views on Tottenham echo former boss Harry Redknapp, who told The Mail last month that Pochettino's debut season had been rescued by young players.
The former Southampton boss has been joined at the club by ex-Saints scout Paul Mitchell, who he told The Mirror he is looking forward to working with in the transfer market this summer. Next season the aim is to be better than purely 'ok', and this means qualifying for the Champions League.
