Porto vs Arsenal Tips - Porto to hold Arsenal in Champions League first-leg clash

Arsenal topped their group following an impressive run that saw them lose just once. 

Arsenal have won four of their last seven matches with their opponents. Meanwhile, Porto have won twice, with the other game ending as a draw. 

Porto secured four wins in their six group-games in Europe, with this enough to see the side finish in second in the group. 

While their home and away wins over Shakhtar Donetsk and Antwerp were all fairly comfortable, they were beaten twice by Barcelona. When Porto played quality opposition, they found it tough to get close to their opponents as they dropped six points. 

Heading into their second-leg clash with Arsenal, Porto simply have to still be in the game on the scoreline. A draw in this match would be a good result as it would see all of the pressure piled on the favourites ahead of hosting the clash. 

Arsenal won four of their six Champions League games, but only one of these wins came on the road as they lost to Lens and took a point from PSV. 

Their inability to consistently win on the road is a worry heading into this match, which means the focus may be on staying solid at the back as they try to ensure that they are not behind heading into the return-leg at the Emirates Stadium.

Arsenal will be big favourites to win the match in the second-leg, meaning a draw in the first-leg would actually be a very solid result.
