The Portuguese boss had watched videos of Wallace in his younger years, and he noticed that the Scotland international used to be more keen to take shots on from distance. And Wallace took on board his manager’s advice in Wednesday’s match against Fulham last Saturday.
The former Burnley winger lashed home the winner at Craven Cottage from 35 yards, and he spoke highly of Carvalhal’s influence after the match.
“He does his homework on players and says he saw me about 100 years ago scoring great goals!” Wallace said.
“He has been joking with me all week and telling me to shoot more.
“I love playing for him. I was a bit unsure at first because he is a foreign coach. He didn’t know me but he has been fantastic for me and changed the way I play. I can play on the outside or inside now. It suits me to a tee.”
Wallace’s goal against Fulham is a serious contender to win Wednesday’s goal of the season competition, but Marco Matias did score a belter for the Yorkshire side against Leeds United earlier in the campaign.
The strike should encourage Wallace to take aim from distance more regularly, as he will be keen to start hitting the back of the net plenty more times in 2016 and beyond.
Wallace has made a positive impression at Wednesday since signing in the summer transfer window, but he has only scored three times in 25 appearances.
