Welsh ace Speed, who is likely to be named as Bolton captain in the absence of Jay-Jay Okocha, says that the London club will have all their focus on winning this competition after both the Premiership and Champions League slipped away from their grasp recently.
"They have been a great team for the past 10 years and I feel they have been criticised unfairly somewhat this season. Arsenal will be up for this game - as they are for every one. The FA Cup is the one trophy they can win.
"They will be taking no prisoners on Saturday and we will be prepared for that. Hopefully we can match them." he said
