Adam Forshaw was at the heart of Boro's win at the weekend with a perfect passing performance.
According to football statistics website WhoScored.com, the midfielder successfully completed every one of his 36 passes, with two key passes made, as the Teessiders beat Swansea City 3-0.
He was the only player across the Premier League to play 90 minutes and achieve the feat.
Forshaw has now made exactly 800 passes this season (with 90% accuracy), the most of any Boro player.
In an impressive display against the Swans, Forshaw also won Boro's first penalty of the campaign.
Only Alvaro Negredo (9.2) earned a higher WhoScored match rating than the 25-year-old (7.8) at the weekend, with both Forshaw and Negredo named in WhoScored's Premier League Team of the Week. It is the second time the Spanish striker has been named in the team - the first following his other Boro brace, against Leicester City.
Negredo has been directly involved in half of Boro's goals this season, and won six more aerial duels than any other player in Saturday's meeting (12).
Elsehwere, Fabio da Silva was the game's top tackler (5), Calum Chambers made the most successful clearances (11), and Ben Gibson made the most blocks (2), including preventing one goal-bound effort from Swansea midfielder Leroy Fer.
