Arsenal manager Arsene Wenger will add few changes to his side prior to facing Porto in the UEFA Champions League on Tuesday at the Emirates. Despite suffering a humiliating 2-1 home defeat to Hull City in the Premiership last weekend, Wenger insists that he won't be punishing his players for Saturday's loss. "Sometimes you make changes because you consider your team and the balance in the other team," Wenger told Sky Sports on Monday. "If a player does not play tomorrow it does not mean they are punished. It is rotation. Players cannot play every single game." Meanwhile, Porto boss Jesualdo Ferreira played down talk that the Hull defeat will affect Arsenal's performance against his team. "I don't believe the Hull game will be of influence. These are two completely separate matches," said Ferreira. "In the Champions League teams always play differently. Arsenal use different tactics to the ones they use in the Premier League." Arsenal are currently second in Champions League group H two points behind leaders Porto. Also in the same group, Turkish outfit Fenerbahce will be hoping to make up for their 3-1 loss at Porto when they face Dynamo Kiev at Sukru Sarakoglu.
