- The Chelsea youngster is set to join the Premier League newcomers for the 2020/21 season.
- Slaven Bilic has hinted that he expects Gallagher to play an important role for his team.
- Chelsea are understood to have agreed a contract extension with their academy graduate.
"He will give us something that we don’t have, that dynamic in the midfield, and I am expecting a lot from him.
Gallagher has been attracting interest from many Premier League clubs after a successful year in the second tier, so it's quite a coup for West Brom to get the midfielder.
Last season, Conor impressed at both relegation battlers Charlton and promotion candidates Swansea, making a total of 47 first-team appearances in all competitions, scoring 6 goals and providing 11 assists.
It's understood that Gallagher has already agreed a contract extension with Chelsea ahead of leaving on another loan, as his current deal expires in just two years.
