Newcastle boss Rafa Benitez also endured a disappointing window as the Magpies made a large profit on their transfer activity so they'll face a hard task to improve on last seasons 10th-placed finish.
Mauricio Pochettino has been pathetic this summer in the transfer window and signed not a single player.
The Argentine added: "We have a very good squad, we have very good players and it is not easy to add players that improve that".
"We try and build the team and create our own way of playing, obviously we have been doing that for five weeks, they have been doing that for three years now so obviously they have a big advantage". "We keep coming close, but it's getting to the point now where we've got to start winning trophies".
Less than a month since Pogba scored in the World Cup final to help France lift the trophy, he was thrown straight into action by Mourinho despite just returning to pre-season training this week.
Spurs got their season off to a flying start early on, as Davinson Sanchez flicked on a Christian Eriksen corner into the path of Vertonghen, who diverted the ball just nine millimetres over the line following a Goal-line Decision System review.
Jan Vertonghen's opener at St James' Park on Saturday was quickly cancelled out by Joselu, but Alli then ghosted in unmarked to head home at the back post in the 18th minute, scoring in very similar style to his goal against Sweden in the World Cup quarterfinals. "We want to achieve things", Alli said of the desire of his team-mates to get back as soon as possible.
Apart from Merino (who wasn't starting anyway) we haven't lost anyone who I personally think Rafa would have chose to keep. "I'm happy to score but it's more important to get three points".
"We like playing together, we enjoy it, so we'll just focus on what we have to do on the pitch", the England worldwide said, quoted by the Daily Mail.
"Everyone has been so excited about the prospect of playing in the new Tottenham Hotspur Stadium and I know all at the Club are very disappointed, but determined to clear this final hurdle", league vice president of global Mark Waller said.
"Of course I am not going to complain, it is only we need to take this, be clever and learn and all work together again this week".
