West Bromwich Albion defender Gareth McAuley says Claudio Yacob is key to their success this season.
Yacob started the season late due to injury.
"I would never say Claudio wasn't in form but he certainly has been breaking a lot of things up for us in the last two games and the goal against Arsenal will be in forefront of people's thoughts," said McAuley.
"Him and Youssouf Mulumbu have been doing a great job in the last four games and we have been getting results with that solid block. He is our defensive midfield lynchpin."
