Saracens boss Mark McCall believes that Mako Vunipola and Matt Stevens should both be considered for the Lions squad this summer.
The duo were both in action as Saracens overcame Harlequins at the weekend, with McCall putting their names forward for a spot in Warren Gatland's team.
"I think Warren Gatland will have been watching Vunipola. If they bring five or six props, a prop with a bit of X-factor is worth his weight in gold," he told BBC Sport.
"Matt Stevens, whose not been playing international rugby, but is available for the Lions and played pretty well as well."
Stevens called time on his international career last year.
