Peterborough United full-back has completed his transfer to Bristol Rovers

Sparkes only moved to Posh from Portsmouth last summer for an undisclosed fee, but he became part of a struggling defence before he was loaned out to League Two side Chesterfield in the second-half of last season.

The 24 year-old played 28 times for Posh (23 starts) scoring one goal in an EFL Trophy win over Stevenage. He arrived with a reputation for accurate set-piece deliveries, but little was seen of that in his time at London Road.

Sparkes was signed as soon as £500k full-back Rio Adebisi was ruled out for a lengthy period because of injury last summer. Posh also signed Tayo Edun from Charlton on a short-term contract, while young Harley Mills emerged as a viable left-back alternative.

Mills, the scorer of a great goal in the Vertu Trophy Final win over Birmingham City at Wembley last season which helped clinch the man-of-the-match award, is currently negotiating a new contract with Posh, although he has been linked with a move to Premier League Fulham.

Edun has joined League One side Stockport County after rejecting two new contract offers from Posh.
