[1] At the end of January 2020, Alberts confirmed his move back to his roots to rejoin the Lions, in order to help them with their Super Rugby campaign.

Due to his colossal mass (120 kg) Alberts' bruising runs and bone-crunching tackling, that often constitute "big hits", have made him a crowd favorite and earned him a large following.

During the 2010 Currie Cup semi-final against the Vodacom Blue Bulls Alberts was awarded "Man-of-the-Match" after he put in a solid performance consisting of 21 ball carries gaining 144 metres.

It is after a string of monumental performances for the Sharks that Alberts was named as part of the Springbok squad ahead of the 2010 Northern Hemisphere grand slam tour.

He won his second Springbok cap against Scotland, when he once again came on off the bench and scored a powerful try after plucking the ball from the air in a line out and driving over the whitewash.

Willem Alberts made his run on debut against the Barbarians at Twickenham in the unfamiliar open side flanker berth.

Alberts is the Sharks' leading tackler in their 2011 Super Rugby campaign with an average of 10 tackles per match and is the third highest in the entire tournament with 58.
