Bale has started the season in impressive style, scoring two goals including a superb solo effort in Tottenham’s 3-2 win over Manchester United at Old Trafford.
Adam thinks preventing Bale from performing well will be important, though the Stoke City midfielder refuses to believe Wales are wholly dependent on the Tottenham star.

|12/1||Gareth Bale is 12/1 with Bet365 to score the first goal in a Wales win over Scotland
"I don't think they [Wales] are a one-man team. They've got a number of players, like we have, who can win the game on their day.
"Obviously [Craig] Bellamy's missing now, [Aaron] Ramsay's a top player, Joe Allen at Liverpool, so they've got players at big clubs.
"We're confident we can go there and get three points and try to go to Belgium and get another three."
The 26-year-old angered Bale during a pre-season friendly between Spurs and Adam’s former side Liverpool, but he is unconcerned about any possible fallout when the countries meet, and believes Scotland have been unlucky in their two qualifying matches so far after taking just one point.
He added: "He won't be playing on my side, whoever plays at right-back or left-back can deal with him.
"We did perform to the way we can [against Serbia and Macedonia], sometimes that happens in games, you don't get the rub of the green.
"If we get that in the next two games you never know where that could take us, where we could be finishing come next week.
"I still think there's a lot of improvement in us, even though we never played too bad in the last games.
"The quality that's come in can hopefully raise that again and we can get three points.
"For us as players, it's good to have [Steven Fletcher] in the squad. He's scored a lot of goals no matter what club he's gone to. To add that to what we've already got is very good for us."
