The British and Irish Lions squad will be announced on Thursday when the chosen few will be named to tour South Africa this summer. But their best asset is already known according to Scotland coach Gregor Townsend as Graham Thomas reports. The wisdom and wide experience of Warren Gatland will be the Lions’ key weapon when they take on world champions South Africa this summer, according to Gregor Townsend. Gatland and his attack coach Townsend will be deep in final selection talks next week, ahead of the announcement of the 36-man British and Irish Lions tour squad on Thursday.
