Tottenham were nowhere near their best at the weekend in the defeat to Liverpool.
Spurs slipped to a 2-1 loss at Wembley in the Premier League and a late consolation from Erik Lamela flattered them on the scoreline.
Georginio Wijnaldum and Roberto Firmino were on the scoresheet for the visitors, as the Merseyside club kept up their 100 per cent winning start to the season to extend their lead at the top of the table.
The North London club were unable to really keep up any sustained pressure on their opponents and were carved open on numerous occasions.
Ex-Spurs and Liverpool striker Keane was critical of the former for their display, claiming that they looked well off the pace.
“Same mistakes again [as Watford]. He (Pochettino) won’t be happy today,” Keane told Sky Sports’ televised coverage of Tottenham v Liverpool (2:35, 15 September).
“Against Watford as he said after the game he spoke to a few of the lads, he was nailing them in training and he will do the same again.
“That was a poor performance and they were sloppy again.”
Spurs have now lost back-to-back matches in the league, as they were beaten away at Watford before the international break.
They missed the extra creativity in the final third of injured playmaker Dele Alli, while number two goalkeeper Michel Vorm didn’t cover himself in glory in place of the injured Hugo Lloris.
Pochettino’s side travel to Inter Milan in the Champions League during mid-week and will be under pressure to turn around the mini slump in results.
