Mascherano: Barca have had ''defensive problems''

Arsenal had a poor start, as they dropped their first two games - 2-1 against Dinamo Zagreb and 3-2 against Olympiakos, which put them at the cellar of the group.

Barcelona's star-studded side should ease to another win when it crosses the continent to play at BATE Borisov in the Champions League on Tuesday.

Neymar keeps being Messi, Rakitic back to being himself, and El Blaugrana in control of its group in the Champions League. And they warmed up for this game with a 3-0 win against Malaga on Saturday that featured a goal from talented Portuguese midfielder Andre Gomes.

It leaves the leaders with seven points from three games and with a place in the next round looking ever-more secure, while BATE stay third in the pool with three points. Filip Mladdenovic is BATE Borisov top scorer with 2 goals.

BATE also have Champions League winning experience in their ranks in the form of Alexander Hleb, who was part of the Barca squad that won the competition in 2008/09. Igor Stasevich scored the opening goal for Borisov in the 8 minute and gave his side the lead.

Leverkusen established a two-goal lead within 18 minutes before Roma bounced back with four goals.

Arsene Wenger's men delivered at the Emirates Stadium, ending Bayern's run of 12 straight wins with second-half goals from France striker Olivier Giroud and Germany playmaker Mesut Ozil.

Barcelona boss Luis Enrique has denied that Neymar is now playing his best football of the season for the Catalan outfit. A draw away with Italian giants Roma was followed by a hard-fought 2-1 victory over Bayer Leverkusen at Camp Nou last time out.

While the visitors made hard work of their win, Barca sit three points clear at the midway point of the group, with Luis Enrique now waiting on the extent of Roberto's injury, with their ranks already limited by a transfer ban and injuries to Rafinha, Andres Iniesta and Lionel Messi.

Vowing not to repeat the mistakes of his past, the Belarusian has said that his side need to play as a team if they are to have any chance of getting something out of the game. Bayer Leverkusen is second with four, while BATE has three and Roma two.

Barcelona conceded just 21 goals in 38 La Liga games last season, as they stormed to the treble.
