Eidur Gudjohnsen among four new signings for Stoke

Gudjohnsen spent six years at Chelsea from 2000

Stoke have signed Eidur Gudjohnsen, Jermaine Pennant, Marc Wilson and Salif Diao on a busy transfer deadline day.

Gudjohnsen has signed a permanent, one-year deal from French club Monaco, while Pennant has joined until January from Spanish side Real Zaragoza.

Portsmouth's Wilson has joined in a player-plus-cash deal, with Liam Lawrence and Dave Kitson moving in the other direction.

Diao, 33, has re-signed for Stoke, penning a two-year deal.

The Senegal international midfielder left at the end of last season, when his previous contract expired, and had been exploring the prospect of a move abroad.

"It is fantastic. He is not only an experienced head, but a good person to have around," said manager Tony Pulis.

"We made it perfectly clear there would always be a welcome for him back here and we're delighted he has signed now."

Diao joined Stoke in a permanent deal from Liverpool in 2007 after an initial loan spell.

His new contract includes an international ambassadorial role, and he said he felt he owed a debt of gratitude to Pulis.

"It's great to be back home. I love the club and I love the supporters, so I always hoped something could be sorted out," he said.

"I feel there is still unfinished business and I want to help Stoke City continue the excellent progress made in my time here.

"Tony Pulis is more than a manager to me and I want to repay the faith that he has shown in my ability at this stage in my career.

"I believe I can still make a big contribution as a player but it is also very exciting that I have another important role to play which could help bring new talent to the club in the future."

Gudjohnsen, 31, had spent the second half of last season on loan at Tottenham where he scored two goals in 14 games.

The former Bolton, Chelsea and Barcelona player was shown around City's new £7m training facility at Clayton Wood before entering into negotiations with the club.

His deal had initially been announced as a loan but upon discovering his contract with the French club was due to expire next summer, they agreed an undisclosed fee to make the move permanent.

The versatile Wilson, 23, was the Portsmouth captain and Pompey manager Steve Cotterill wanted to keep him at the club.

But after signing a four-year deal at Stoke, Wilson said: "It is great to be back in the Premier League.

"I had a taste of playing in the Premier League last season, it is the best league in the world and I wanted to get back there as soon as possible."

Pennant, 27, started his career with Notts County before joining Arsenal for £2m as a 15-year-old in 1999.

The England Under-21 international has also played for Watford, Leeds, Birmingham, Liverpool and Portsmouth before he moved to Spain in 2009.
