Dermot Gallagher believes Paul Tierney made the correct decision not to send off Liverpool midfielder Wataru Endo.

The Japanese international slid in for a 50-50 challenge with Brentford midfielder Christian Norgaard during the Reds' 3-0 win over the Bees at Anfield on Sunday.

Match referee Tierney didn't stop play for the challenge but the incident was looked at by the VAR at Stockley Park. The challenge occurred shortly before the hour-mark with Liverpool holding a slender lead thanks to Mohamed Salah's first-half effort.

The Egyptian would double the Reds' advantage and his tally for the afternoon shortly after, nodding home from Kostas Tsimikas' cross. Despite the protestations from Thomas Frank, who wagged his finger at the official following the decision to stand by his on-field call after Endo's tackle, Gallagher believes Tierney got the right call.

"I didn't think it was a red card at the time, I don't think it's a red card now," he said. "If it's a foul, which the referee doesn't think (it is), he's low, they're both going for the ball, both keen to get the ball. For me, it's not an act of serious foul play.

"The referee has the best view so the referee knows, the speed he's come at, he's got the best view. Not a red card."

Throughout the opening months of the Premier League and European seasons, there have been some contentious red cards. Liverpool have been on the wrong end of some of them, including Alexis Mac Allister's against AFC Bournemouth - which was later rescinded - and Curtis Jones' in the defeat to Tottenham Hotspur.

More recently, Cristian Romero and Marcus Rashford have been shown straight red cards for high challenges in the English top-flight and Champions League respectively.

The incident involving Endo and Norgaard left Frank fuming. The Dane called for consistency after the likes of Jones and Rashford were shown red cards, even though he didn't agree with the decision at the time.

"I think it's a clear free-kick and at least a yellow card on the pitch," he said. "I think these situations are not a red card. But in the VAR world, where we have slow motion, and you freeze it and he clearly goes over the ball with too much force onto the leg of Norgaard.

"Then I think, if Rashford's is a red, Curtis Jones' is a red, Josh Dasilva's is a red - then I think this is also a clear red. I don't think any of them should be, but in this era apparently, it is a clear red. I would just like to have that consistency."
