Red-hot Danny Welbeck has an immediate chance to boost Arsenal

Arsene Wenger probably has more fingers crossed than most managers during the international break. Arsenal always seem to suffer an injury or two, so maybe we shouldn't be too surprised to hear Aaron Ramsey got an ankle knock while on Wales duty as they squeezed past minnows Andorra.

Blame their pitch for Ramsey's turned ankle. Well, Wales boss Chris Coleman did, but Ramsey hopes to be fit to face Manchester City on Saturday. On top of that, Arsenal will be checking bumps and bruises after England's win in Switzerland, France's get-together with Serbia and, of course, whether Mesut Ozil will be fit, because he got an ankle knock before Germany met up.

But more encouragingly, Arsenal welcome back Danny Welbeck from England duty. He moved down south the day after England won in Switzerland, and he scored twice.

Arsenal are getting a player who is bang in form and full of confidence for their 16 million pounds. Welbeck will get the chance to play through the middle. In the future, he could even team up with Theo Walcott and Alexis Sanchez as part of a three-man strike force. Imagine the speed of that attack!

Walcott spoke encouragingly and optimistically this week about playing with Welbeck and how Arsenal could have the fastest striker force in the Premier League. Welbeck has real pace; he can finish well as he proved for England in Switzerland and he loves to lead counterattacks. Basically, use him as a central striker and Welbeck will seize the moment.

He cost as much as Mario Balotelli did for Liverpool. But who got the better deal? Balotelli is regarded as a lethal finisher but his reputation as being world-class has been checked because of his wild off-the-field reputation. If Liverpool can "tame" mad Mario then they will have a wonderful striker on their hands. A truly fantastic talent.

Welbeck, meanwhile, is more about proving himself on the pitch. There's been some great promise and potential, but he admitted this week that the last run of games he's had up front was as long ago as Christmas.

So Welbeck will want to prove himself as a striker for Arsenal. In 53 starts for Manchester United, he scored 20 goals in the Premier League. That's a great return and ratio.

Arsenal will need a lethal finisher against City, and this is Welbeck's big chance. People say he's got a great attitude and spirit. He could be a fantastic signing, and with the determination to prove his point he really has got the motivation.

It's also a big week for Arsenal. They've got City at the weekend, followed by Borussia Dortmund in the Champions League. Two strong results will really lift the mood.

But Welbeck has already done that, bringing a feel-good factor with him to the Emirates. They have bought a really talented player, and if he can score on Saturday he will be an instant hit. My money is on him to be a huge success for Arsenal and England, not just now but in the long term as well.
