Liverpool manager Brendan Rodgers believes that Marco Steller will be Basel's biggest threat tonight.
Streller leads the line for Basel and he will be looking to cause a Liverpool backline, which has struggled so far this season, more problems.
However, Rodgers insists that he is thoroughly prepared for the challenges that he will face at St. Jakob's Park.
"They have quick players and they have their captain, Marco Streller, who is someone that scores goals regularly," he said to the club's official site. "I think we've seen enough of them."
"It will be a tough game for us. They're regular performers in the Champions League, so they know the level, they know the experiences and we've seen that they are a very good side."
"They are the top team in Switzerland and I think it's going to be a tough game. We're really relishing and looking forward to it."
Streller is Basel's most experienced star and they will be relying on him to have a good performance if they are to pull off an upset tonight.
The 33-year-old has accumulated 86 goals in 189 appearances for the Swiss side since joining in 2007 and he will be desperate to improve this record tonight.
Although Basel are not one of the most reputed sides in the competition they have proven they can cope and Liverpool will be under no illusions of the difficulty of the task that lies in prospect.
In their first game of the tournament, Rodgers' men were considerably off the pace as they scraped past Ludogorets and another display of that standard will surely see them come away empty handed.
The pressure has mounted on Liverpool after a poor start to the campaign, but they will be looking to kick-start and begin to build some confidence here, as well as take a big step closer to qualification for the next round.
