The Arsenal defender believes that the Lille star's transfer to the Blues will prove beneficial to the club and the Premier League as a whole but may also improve Belgian football
The 21-year-old tweeted last week that he would be joining the 'Champions League winner' this summer, after a drawn-out transfer saga concerning his future.
Chelsea have so far declined to comment on the speculation that they have seen off both Manchester clubs in the race for his signature, but it appears certain that he will become a Blues player this summer for a £32 million fee.
Vermaelen believes that whoever Hazard ends up playing for in the Premier League next season, it will prove money well spent.
The Gunners' Belgian centre-back told the media: "I think he is a great player. Technically he is one of the best in our [Belgium national] team. I don't know if I am surprised he chose Chelsea ahead of [Manchester] City because I was not there behind the scenes.
"He made his mind up and I think he will do well, I am convinced he will."
Vermaelen has been in England for three years now and feels that the addition of Hazard, one of Europe's most sought-after prodigies, to the current crop of Belgian footballers in this country can only aid the national side.
The former Ajax player added: "I am happy he came to England, I think it is good for the national team as well."
