Thompson, who spent the past two years with the Bulldogs before joining Widnes, is expecting Roosters and Cowboys victories.
“I think both the Cowboys and Roosters should win but Broncos and Wigan will be a good game,” he told Love Rugby League.
“That game will be close.”
Thompson bagged a hat-trick in the Vikings demolition of Leeds last weekend. Widnes face Salford, fresh from their win against Saints, on Sunday.
“Salford are going to be tough to beat at their home,” he said.
