That's a performance Wenger is also hoping Wilshere will be able to replicate, and said he shouldn't change his playing style despite the number of serious injuries he has suffered since then.

Arsenal have dropped out of the Champions League for the first time in 20 years, but Arsene Wenger is still adamant that he would rather that the club return to the Top Four to guarantee Champions League football next season, rather than win the Europa League, like Manchester United did last season.

In another incident, six people died after drowning in river Ganga, in Bihar's Maranchi district. On getting the information, police reached the spot and started the rescue operation.
"His game, you have certainly seen the video of him when we played against Barcelona, his game is about that", Wenger said, highlighting a particularly impressive display against the Catalan giants in 2011.

His recent return to action in the under-23s ended unhappily as he was sent off for a brawl with a young opponent. "Some just come back like nothing happened to them, so are traumatised for their whole life".
"The disadvantage is of course that he was out of the game for a long time but there are advantages as well". "I had a conversation with him, but I didn't have to raise his spirits at all".
