Dinamo Zagreb v Arsenal

Saudis, UAE, Bahrain to compete at Gulf Cup

Arsenal face a tricky trip to Croatia as their Champions League Group F campaign gets underway against Dinamo Zagreb on Wednesday.

The Gunners have qualified for Europe's premier club competition for 18 straight seasons, while they have reached the knockout stages for the past 12 years.

However, their defeat to Monaco on away goals last term saw Arsene Wenger's side also fail to progress past the last-16 for a fifth time in succession.

Their first group opponents are likely to pose a stern test, though, with the Blues in the midst of a 41-match unbeaten run in all competitions stretching back to November 2014.

The north Londoners themselves have not tasted defeat since the opening day of the Premier League season, when they went down 2-0 to West Ham.

Wenger was dealt a massive blow in the build-up to the midweek encounter with the news that Jack Wilshere requires a leg operation, which will rule him out of action for about three months.

Wilshere is joined on the treatment table by fellow midfielder Thomas Rosicky and striker Danny Welbeck, who are both likely sidelined until the end of the year.

Theo Walcott started up front against Stoke on Saturday, scoring in a 2-0 win and the forward could find himself in the lone striker's role again in Zagreb.

Meanwhile, the hosts will have to do without midfielder Goncalo Santos, who is serving a suspension.
