West Brom boss Di Matteo hails Tchoyi influence in Man Utd fightback
Di Matteo handed the Cameroon international his full Barclays Premier League debut on the right wing, with Graham Dorrans the man to make way in a reshuffled midfield.
And the head coach later explained why it was too soon to start key player Jerome Thomas at Old Trafford, preferring to utilise him as a 69th-minute substitute for Tchoyi on his comeback from a three-week calf injury lay-off.
"Jerome's only trained with the team twice in the last three weeks so he didn't have more than 25 minutes in his legs," Di Matteo told the WBA website.
"Tchoyi's got different characteristics and ability to Graham.
"He's more of a wide player than Graham and I thought with his long legs he might be able to stretch the opposition.
"I have a lot of faith in my squad.
"When I talk, I always talk about the squad because everyone is important.
"We know when someone is suspended or injured someone else can come into the team and we expect them to do well.
"It seems to be working at the moment."
