The only game they have lost in 2014 came on New Year's Day as they were beaten by Chelsea, who are now top the table, at Stamford Bridge.
A delighted Pochettino said: "We are having a 2014 that is excellent.
"We are having great performances, the team is playing very well and overall we are very happy with the performances of the team as of late.
"I want again to congratulate the players because we have a short squad, not that many players in the squad.
"We also have a lot of young players who are still learning and in light of that we are playing very well and we are very happy about that."
