After a weekend dominated by headlines about the arrival of Bale, it was the omission from the Spurs squad of Alli that provided an intriguing subplot.
So far, Alli has played just 45 minutes of football this season, starting in the 1-0 defeat by Everton in Spurs’ Premier League opener before being replaced at half-time.
Prior to Sunday’s win, Mourinho said only of Alli’s exclusion from the squad that he had “too many players” in certain positions.
Asked afterwards whether Alli had a future at Tottenham, the manager responded positively, saying: “Yes, of course.”
But when pressed on whether he wants to keep him, the Portuguese coach was a little more vague.
“I want a balanced squad – that’s what I want,” he said. “He doesn’t need to be sacrificed for that but a squad is a puzzle.”
Stay and fight or on the move – what next for Alli?
Despite missing the past two games for Tottenham, Alli is set to earn a recall for their next game – the Carabao Cup third-round trip to Leyton Orient.
“He will play on Tuesday,” added Mourinho. “He’s fresh. He has to be motivated by being out of the squad for a couple of matches.
“Tuesday is a knockout game and it’s a big opportunity for him to show how good he is because we know he is very good.”
His new status – having to prove himself against League Two opponents – is a fall from grace for a player who at one stage was among the first names on the teamsheet for club and country but who is now out of favour for both.
Mourinho hinted on Sunday that players might need to leave in order for him to trim the size of his squad, and in addition to PSG’s interest in Alli, Real Madrid are also reportedly keeping an eye on the situation.
“We have a huge squad, a squad with numbers that are very difficult to manage,” Mourinho said. “I never had it, I don’t like to have it and it’s not easy for me.
“I start with Son [Heung-min], with Lucas [Moura] and with Harry Kane and on the bench I still have Moussa Sissoko, Erik Lamela and Steven Bergwijn.
“We have too many players for some positions and some of them are paying the price for this.”
From certain starter to out of the team
After joining Tottenham from MK Dons in 2015 Alli developed into one of Europe’s most prized attackers under former boss Mauricio Pochettino.
