Mauricio Pochettino said his Tottenham side got off to a poor start in their Premier League opener with Everton on Saturday, with a hamstring injury to captain Hugo Lloris compounding their woes.
A much improved second half saw Spurs leave Goodison Park with a 1-1 draw after Erik Lamela cancelled out Ross Barkley's fifth-minute opener.
Speaking to the club's official website, Pochettino explained: "It's the first game of the season and it's always difficult.
"The first half was difficult for different reasons because they scored early and then Hugo was injured.
"In the second half we fixed some things and we played much better and deserved the draw, and had chances to win the game. We were unlucky. I was happy with the performance and now we need to follow up."
On the extent of the injury sustained by Lloris, the Argentine boss added: "We will need to assess Hugo tomorrow and we'll see what happens. It's a hamstring."
New signing Vincent Janssen made his Spurs debut, and while the Dutchman may not have scored, it was the change in personnel as Pochettino withdrew Eric Dier, that allowed Spurs to alter the game and find an all-important equaliser.
Janssen may well have scored on debut but for the heroics of new Toffees goalkeeper Maarten Stekelenburg who denied his compatriot with an excellent close-range save late on.
Mauricio added: "He [Janssen] complemented Harry and both played very well. Vincent is a different type of striker and it was perfect, I was happy with his performance.
"I think Stekelenburg was man of the match and that speaks a lot about how it was in the last 45 minutes."
