Arsenal's Thomas Vermaelen has missed three rounds of training due to an injury, which means he won't be able to play for the rest of the season.

The Dutchman, who was named in the England squad for the World Cup last summer, is currently recovering from a knee injury sustained during his club career. He had surgery on his knee earlier this month and will likely miss most of the upcoming matches.

Vermaelen's absence could have a big impact on Arsenal's chances of winning the Premier League title next season. They need to find a way to get him back into shape before they can compete with their rivals for the title.

It remains to be seen how long Vermaelen will be out of action, but it's clear that the club needs to make quick decisions in order to keep him healthy enough to return to the pitch. The team's manager, Arsene Wenger, has already expressed his frustration at not being able to use Vermaelen in the first-team lineup.

Despite the setback, Wenger has shown a willingness to make changes when necessary. He has brought in some experienced players to help fill the void left by Vermaelen, such as Pierre-Emerick Aubameyang and Mesut Ozil.

However, if Vermaelen cannot recover quickly, it will be difficult for Arsenal to maintain their current form and challenge for the top spot in the league. With so many talented players on the roster, any mistakes or injuries could cost them dearly.
