West Brom have re-signed midfielder Zoltan Gera on a one-year deal.
The 34-year-old Hungary international was released by the Baggies at the end of last season after missing the final months of the campaign with a anterior cruciate ligament knee injury but was invited back to train with the squad over the summer.
"It's great to have Zoltan on board for another season," Clarke said. "He's a top professional and good within the group.
"I believe his form last season before his injury was as good as at any time in his career and our main aim is to get him back to that level as quickly as possible.
"If he reaches that level again, he will be a great asset for us."
Gera, who made 18 appearances before his season was ended by injury, is scheduled to return to full training on Monday week and should be available for first-team selection in early October.
West Brom's sporting and technical director Richard Garlick added: "I'm delighted we've managed to agree a deal that suits all parties.
"It's been well documented that Zoltan has had rotten luck with injuries over the past couple of years but when he has played he has been different class. The amount of goals and assists he provided last season underlines this.
"He has worked extremely hard to get himself fit and we're looking forward to seeing him pull on an Albion shirt again in the near future."
Gera is effectively now in his third stint at The Hawthorns. He first joined the club from Ferencvaros in 2004 and made 155 appearances before joining Fulham in 2008.
He returned to Albion on a free transfer in August 2011.
