Adam Armstrong has joined Southampton after leaving Championship club Blackburn Rovers and Newcastle United legend Alan Shearer has provided an instant reaction to the move on Twitter.

The English striker was linked with a return to St James’ Park before the Saints completed a move for him, but the Magpies have a 40 percent sell-on agreement and are due a windfall following the deal.

Newcastle have missed out on a quality hitman, but Shearer has wished him well on his return to the English top-flight.

Good luck @AdamArma9 at a brilliant football club.
