BRENT Sancho turned down an 18-month deal at Doncaster to join the Lions this week.
The 31-year-old defender signed for Millwall and went straight into the reserves against Charlton on Wednesday - his first competitive action since last season.
The Trinidad & Tobago World Cup star has been chased by five clubs since leaving Gillingham in May, after a row with chairman Paul Scally.
But he's wanted to work for Kenny Jackett since March 2006, when the then-Swansea boss tried to sign him on loan.
Sancho, who had a trial with the Lions in the summer, said: "Five or six clubs wanted me, including one in Greece, but I was patient and it's paid off. There is no better place to be than Millwall under Kenny.He is a phenomenal guy."
Sancho also had a very round trip to get to The Den from Gillingham. He needed a work permit and had to leave the country while the application was processed, so spent a nervous weekend in Dublin waiting to hear if he'd been given one.
He was on the first flight back once he heard from agent Stephen Davies of DMC Blackstar that it had gone through.
"I had to go to Ireland to basically sit in a hotel room for a few days," said Sancho."It's a lovely city but I couldn't enjoy it while I was so anxious.
"I was very upset at the way I left Gillingham because I am not the sort of person to fall out with anyone at all. It was sad because it affected my chances of getting another club.
"Now I'm really looking forward to repaying Kenny's faith in me by grabbing my chance with both hands.I feel very lucky.
"Even with all the injured play-ers,we have a good squad, an excellent boss and great fans - we're a lot better than our league positon.
"There's a long way to go, but I genuinely think we can challenge for promotion under Kenny."
Jackett said: "Brent is a mature defender who can pass his experience on to some of our younger play-ers.He now has the chance to prove he is worth a longer deal."
