Tick tock.

Wales boss Warren Gatland has labelled England tighthead prop Kyle Sinckler as a bit of a “timebomb” ahead of this weekend’s crucial Six Nations fixture between the two sides at the Principality Stadium in Cardiff.

Gatland coached Sinckler on the 2017 British and Irish Lions tour of New Zealand, and while he thinks Sinckler is “a very good player”, his temperament can let him down at times and says “other players are aware” of that.

“I think the thing with Kyle, there is no doubt he’s a very good player in terms of his carrying, scrummaging and work-rate.” Gatland said.

“There is a challenge sometimes with his temperament. He’s aware of it. Other players are aware of it. We’ve already seen in the Six Nations that he has been involved in a couple of incidents.”

“Hopefully, we don’t get dragged into that on Saturday. Emotionally, he can be a bit of a timebomb. I am not saying anything that people aren’t aware of.”

But Gatland insisted his side will not target Sinckler’s temperament on Saturday.

“Look, we won’t be going out there trying to antagonise him, because that’s not in our make-up. We will just go out there and play.”
