Ex-Tottenham boss Tim Sherwood feels a spell at Millwall was the making of Harry Kane.
Sherwood checked on Kane during a past loan at Millwall.
He told the Daily Express: "When he went to Millwall, I went to watch him a few times.
"It was the most hostile atmosphere imaginable and he wasn't having the best of times - because he was a Tottenham boy he was getting hammered.
"One of our scouts came back to the club and told the manager at the time Harry Redknapp, 'You've got to get Harry back out of Millwall'.
"Luckily I overheard the conversation and stepped in. 'Where do you want him to go?' I asked. 'Some club where he smashes the ball 40 yards over the bar and it doesn't matter because the crowd give him a clap?' It was character-building - the making of the man.
"He ended up scoring seven goals in the final 14 games of the season and was named the club's young player of the year. It was one of the most successful loan spells he had.
"A lot of players could have gone under, but he could handle it. He is a tough cookie."
