Silvestre left the Emirates when his contract expired during the summer amid reports his frustration at a lack of game time had boiled over.

But, ahead of tomorrow's Champions League Group A clash with Tottenham, the 33-year-old sidestepped questions about whether there was any lingering resentment over his departure.

"There must be a reason why Sol Campbell, William Gallas and myself all left the club," he said.

"But it's not the place to discuss that.

"I'm just happy for Arsenal to continue the way they do.

"I still watch their results and some highlights because I care about my (former) team-mates and the staff.

"I had a good time over there, so I'm not going to complain.

"Now I'm focusing on Werder 100%."

Tomorrow could see Silvestre reunited with Gallas, who made the controversial decision to cross the north London divide last month.

"I don't know if I would've taken that decision," said Silvestre.

"But when there was speculation about William joining Tottenham, I was almost sure that he was going to sign.

"William does not listen to anybody else but himself - and that's his choice.

"If you ask me if he made the right decision, I would say - for him - yes, because he's happy, he's playing, he's in London, his family are there.

"I'm also happy to face him tomorrow."

He added: "I think William can give a lot to Tottenham with his experience in that competition and at international level.

"I'm sure that he will bring a lot because he's a warrior and he's going to show the way to the Tottenham defence and the whole team."

Saturday saw both players make their debuts for their new clubs, with Silvestre helping Bremen keep a clean sheet in their Bundesliga draw at Bayern Munich.

Asked how he was feeling physically, he joked: "We came back from Munich, we went to bed, and I only woke up this afternoon before training!"

Tomorrow's game also reunites Silvestre with Spurs, who he faced many times with both Manchester United and Arsenal.

The Frenchman reads nothing into the visitors' lack of Champions League experience, pointing out most of their players had played in big games for their countries.

Silvestre got his chance in the Bremen side following injuries to Per Mertesacker and Naldo, with head coach Thomas Schaaf deciding to field him in the centre of defence rather than at left-back.

That should see him come up against Peter Crouch tomorrow, and he said of the beanpole striker: "He's got the height to climb above any defender in the world.

"But his quality will be his position in the box because it's not only about being taller - you have to be at the right place at the right moment.

"Peter Crouch, because he's not fast and he's less skilful than the other players, he's less rated.

"But it's always dangerous to play against him."
