Tottenham Hotspur have a gruelling schedule next week where they face three huge matches in six days.
Spurs are planning to compete domestically and in Europe this season, and they have an action packed month in the pipeline.
The Lilywhites are off until Saturday, but after that they face three huge games in a six day period, and Pochettino says that poses some difficulties for his team.
“It’s going well but you know in football things can change quickly and with that in mind, we have to keep working hard and focus on every game,” Pochettino said.
“Now we have a week to prepare for [Aston] Villa and then the schedule is difficult - Villa in the Premier League on Monday, Anderlecht on Thursday and then Arsenal. But we are strong and our mentality is strong.”
Pochettino's side have made an encouraging start to their Premier League campaign, and beat Bournemouth 5-1 in their latest outing.
That win extended their unbeaten streak to nine matches, and it also pushed the north London club up to sixth place in the Premier League table.
However, Tottenham's next three matches will be massive to their campaign, and could define whether their start is still reflected on as a good one in a fortnight's time.
If Tottenham can beat Villa and Arsenal they will have a good chance of breaking into the top-four, while a win over Anderlecht will put them in a strong position to qualify from their group in the Europa League.
Defeats in any of the matches could destroy the momentum that they have built up, though, and Pochettino will hope that his side can keep their good form up over their most testing period of the campaign to date.
