Evans arrived at the Hawthorns from Manchester United in the summer transfer window, and at the time Sessegnon was on the fringes of the first team.
The Benin international has forced his way into Tony Pulis’ starting line up recently though, and Evans is unsurprised to see the attacking midfielder excelling.
"When I first joined he wasn't really in the team, but you could see a lot of quality from him in training,” the central defender said.
"The manager put him in and he hasn't looked back.
"He's fantastic in the final third at beating people and I certainly wouldn't like to be playing against him.”
Sessegnon set West Brom on their way to a 2-1 victory against Stoke City, with Evans netting the winner.
Sessegnon’s goal was his first of the campaign, and it should help to further establish his position in Tony Pulis’ starting team.
The former Sunderland man has now featured in 11 of the Baggies’ Premier League matches, having failed to make an appearance until October.
