Sinclair moved to the Etihad Stadium last summer as a replacement for the outgoing Adam Johnson after forging a stellar reputation with solid performances for Swansea.
Despite this, the 24-year-old has had a torrid time at City and has failed to make an impact at the club. A measly 11 appearances last season were simply not enough for the winger to progress as a player, with only two of those in the starting XI.
West Brom manager Steve Clarke is glad to have brought the ex-Swansea man to the Hawthorns and knows the player well after working with him at Chelsea.
"Scott understands he needs to play football and it will be good to work with him again," Clarke said.
"We're delighted he feels this is the right club for him at this stage of his career. He is the type of player we were missing from the squad.
"He is a pure winger, who is quick, direct and scores goals - he has proven that over his career. He can play off the right or left and improves our attacking options.
"I know him well and he is a good person, who I know is 100 per cent committed to our cause.
"He is frustrated he did not get the chances to play at Man City last season and hopefully he will take those frustrations out on Premier League defenders this season."
Sinclair has turned into something of a forgotten man. Even while at Chelsea big things were expected of the sprightly wideman and his potential came to fruition at the Liberty Stadium.
He has been unlucky that he joined arguably the most competitive Premier League squad in the form of City’s, and will relish the opportunity to get out and play regularly again.
For West Brom, it certainly has the potential to be a bit of inspired business. If Clarke can get Sinclair back to the form that earned him a move to City, the Baggies faithful may well have a new hero. Sinclair’s last season at Swansea was the Welsh club’s first in the Premier League, and he played a major role in helping the side exceed expectations.
Sinclair’s pace and threat wide will be an asset to West Brom’s attack, but the new man has another responsibility after the move. Goals. The Baggies are struggling in attack with Romelu Lukaku leaving after a loan spell, and Nicolas Anelka has just been given compassionate leave.
Sinclair netted 30 goals in two full seasons at Swansea, and if the new man can get anywhere near the double-figure mark this season for West Brom it could well prove invaluable.
