The Portuguese midfielder never made a first team appearance at Tottenham, but has impressed Tony Mowbray enough on trial to earn a two-year contract.
Coventry City confirmed the signing of former Tottenham Hotspur attacking midfielder Ruben Lameiras on a free transfer on Friday, signing the youngster up on a two-year contract according to their website.
The Portuguese winger spent the last few months of the season on loan at Atvidabergs in the Swedish Allsvenskan, where he made 11 appearances as the league campaign began in Scandinavia.
His contract was due to expire at Spurs in June, and Lameiras could have extended his deal in Sweden if he wished.
But this summer he decided to cancel his loan and return to the UK, and the 20-year-old has impressed while on trial for the Sky Blues, with Tony Mowbray name checking the Portuguese for his attacking ability and skill after recent matches.
Having signed Lumerias, the former West Brom manager had this to say about his new arrival on the Coventry website: "We've had the chance to work with Ruben for more than a week now and in that time, he has really impressed us.
"He's got a great work ethic and whilst we know he isn't the finished article, we see plenty of potential for him to progress with us and make an impact.
"Ruben can play central or on the wings so once again, we've got another player who can be a valuable option for us across the park."
Lameiras spent four years at White Hart Lane, and is recorded as playing 24 matches in the club's development side earlier this season, scoring 4 times and assisting 4 more.
He will now try his hand in League One, and will effectively be replacing former Spurs loanee Grant Ward, who impressed on loan at the end of last season, with the 20-year-old Englishman instead loaned out to Rotherham United in the Championship for the coming season.
