Former Liverpool winger Xherdan Shaqiri believes his old club can win the quadruple this season, as the EFL Cup winners prepare to host Inter in the Champions League.

The 30-year-old, who is now plying his trade in Major League Soccer after joining Chicago Fire in February, won the Champions League, Premier League, and FIFA Club World cup titles in a three-year spell at Anfield.

Jurgen Klopp's side defeated Chelsea to win the EFL Cup last month, and are preparing for a Champions League second-leg clash with the Italian champions, boasting a 2-0 lead from the first leg at San Siro.

With the Reds sitting just six points behind Premier League leaders Manchester City and advancing to the quarter-finals of the FA Cup, recent talk has surrounded the prospect of Klopp's men completing an unprecedented quadruple this term.

Shaqiri, who scored eight goals in 63 appearances for the club, has talked up their chances of doing so, as long as the Reds can keep their key players fit.

"They must do everything perfect, to win everything", Shaqiri told Sky Sports. 

"But if one team can do it, then for sure Liverpool is one of them.

"I think it's important to go from competition to competition, because there are so many with the Carabao [EFL Cup], FA Cup, and they are still in all of these competitions.

"Everyone needs to be fit and healthy, because injuries as you know are always difficult to deal with, but Liverpool have a great team and they dealt until now with everything.

"I'm really looking forward to the end of the season, [to see] how they're going to finish, but everything is possible." 

Liverpool's recent EFL Cup triumph represented the 10th major trophy of Klopp's coaching career, and the in-form Anfield side have not lost a game in any competition since a 1-0 reverse to Leicester City on December 28th.

Heading into their clash with Inter, Liverpool have also won all seven of their Champions League games this season.

Excluding qualifiers, they could become just the third team in the history of the competition to win their opening eight games in a single edition of the tournament, after Barcelona in 2002-03 and Bayern Munich in 2019-20.
