When one British and Irish Lions Test full back is injured, Wales are blessed another one can slot directly in.
Leigh half-penny looks set to miss out the Six Nations opener against France on 1 February, after being eliminated for a further three to four weeks with a concussion injury he suffered on 10 November.
Half penny has been the 2013 Lions man of this series from Australia, but step forward Liam Williams – the 2017 Lions full back in three Tests against New Zealand, and now favourite to wear the exact Wales 15 jersey at Paris.
There are other choices for head coach Warren Gatland at Jonah Holmes, Hallam Amos and Gareth Anscombe, but Williams is the man in possession after starting at full back against South Africa – the last of Wales’ four fall Test victories.
That came just a week after playing the wing along with scoring two tries against Tonga on his 50th cap.
“I’ll play anywhere, so exactly what is going to be will be,” said the 27-year-old.
“I really don’t pick teams so we are going to need to wait and watch. There exists a good deal of rivalry [from the trunk three] which is healthy leading up to this worldcup.
“The fall internationals success put us in good stead for the Nations.”
“Any game Liam has played over the last 18 months in full-back he was well – great actually,” said McCall.
“He’s Test experience there and would be a pretty good replacement for Leigh if he can’t create it.
“Liam is among the very competitive and committed players I’ve come across, along with some worldclass abilities, specially in the air.”
Williams is more focused on half penny’s health and bid to go back to full form and fitnesscenter.
“I’ve spoken to him he says his head is not exactly ready yet,” said Williams.
“There’s nothing worse than needing concussion and seeking to run and also you’ve got headaches.
“You only get one headset and you will need to check after it. It’s rough, but Leigh needs to make sure he is right and ready to play .”
Williams has already established his own injury concerns, returning to Saracens after the fall internationals and promptly tearing his hamstring in his first week back.
He also missed the following six weeks and began his come back with a tentative 53-minute return within the English Premiership defeat by Sale past Friday.
This setback came after a constant groin injury curtailed his engagement in his first Saracens season, once the negative were crowned English champions.
“To come back from four weeks together with Wales and and maybe not even play a game was so frustrating but that’s just the way it moves,” said Williams.
“They have handled me well during the previous number of years and I only need to remain healthy.”
Trying to Find longer Saracens silverware
Williams demonstrated his ability with just two hat-tricks earlier previously and McCall expects to see more of him on the pitch.
“Liam is actually a class player however it has been stop-start for him personally and he has not strung five or even six performances together to people,” said McCall.
“Fingers crossed he is able to get through three games for us and then goes through the Six Nations and now we get him to the end of the year”
Williams will continue his return from the Champions Cup game in Lyon on Sunday. Saracens are unbeaten in Europe so far this season with four wins from four and hopes of regaining the title they won at 2016 and 2017.
“the main reason I came here was to acquire trophies,” said Williams.
“Things did not move right [in Europe] this past year and we are trying to place right this season.
“We set ourselves high standards and we aren’t exactly there that this year and there is still more to come back .”
Williams has established a winner with the Saracens squad.
“He’s been magnificent and is a very common member of this group and also do you know what it is you’re likely to get from him weekly – total commitment and competiveness.”
As the only Welshman in Sarries, playing alongside almost half the England Test side, together with Maro Itoje, Jamie George, Billy Vunipola, Mako Vunipola and Owen Farrell among his team mates, he has also been exposed to exactly what he now describes as”some terrible banter”.
“They state it and stuff goes into one ear and out the other,” he said.
“I have not played against them yet for Wales since I’ve already been here because I was hurt at the previous six Nations.
“Hopefully I can remain healthy and play them .”
