The England captain damaged his ankle ligaments against Manchester City in the quarter-final of the Champions League in April but battled back to make the starting line-up for the final on Saturday.
A below-par performance in the 2-0 defeat to Liverpool, though, has raised question marks over whether it is right to expect him to the lead the country in tonight’s semi-final against Holland just five days later.
On the back of playing all 90 minutes of the game in Madrid, though, Kane feels he is more than ready to go again.
“With injuries, it’s never easy,” he said. “I was out for eight weeks. You do as much as you can to be fit.
“But I’ve been training for a few weeks and played on Saturday and I’ve had no problems.”
Southgate, who made a point of going out to Madrid to perform his own personal scouting mission, was determined to keep his cards close to his chest.
“I’m not prepared to say whether Harry Kane is playing tomorrow,” he said emphatically.
Moreover, he warned that England had moved on from the days when the whole nation was left on tenterhooks over the fitness of a single player.
“When I took over, I remember talking about how everything had fallen on Wayne Rooney’s shoulders,” Southgate said. “It was whenever we’d been to major tournaments. I was in Japan and everything was around David Beckham and whether he would be fit.
“We had to build a team where we weren’t reliant upon one player.”
That said, Kane was the World Cup Golden Boot winner and with that pedigree, Southgate also said that the Spurs player could be excused an off day on Saturday.
“I was at the game,” he said. “I wanted to see it. We have our own observations on how that game played out. But a lot of the service that went into Harry, he wasn’t favourite to win it.
“There are many factors. The brilliant thing is we had a lot of English players playing on a massive occasion in both teams.”
Nevertheless, it has left victorious Liverpool captain Jordan Henderson facing a late fitness test and the problem of tactical preparations being disrupted.
“It’s been strange,” Southgate said. “The Champions League players only arrived on Tuesday and there’s been a lot of tactical work to be done. But they’re pretty much all available.
“So you make decisions on the evidence in front of you. We have to prepare a team that we believe can cause the Dutch the maximum problems and can and expose possible weaknesses we see with the mentality that whoever is in the shirt has huge belief and trust from us as a coaching staff.”
ENGLAND PROBABLE TEAM (4-3-3): Pickford; Walker, Stones, Maguire, Chilwell; Henderson, Rice, Barkley; Sterling, Rashford, Sancho.
