Ex-Liverpool defender John Scales believes Luis Suarez could pose John Terry several problems during this weekend's FA Cup final at Wembley.

Both players' recent form has been exemplary, with Suarez having scored a hat-trick in his last outing against Norwich City, while Terry has been influential in The Blues' recent upturn in form which included reaching the Champions League final after defeating Barcelona.

However, when Liverpool and Chelsea renew rivalries this Saturday, Scales, a veteran of two FA Cup finals, believes the Uruguayan will get the upper hand.

Luis Suarez and John Terry
Suarez is expected to give Terry problems.

"It would suit Chelsea if Andy Carroll was playing because he is excellent in the air and that would play to the strengths of the Chelsea defence because he is less mobile than Luis Suarez but they will have to be on their toes to stop him because he is such a mercurial player," he said.

"Suarez kept Liverpool on track for the final with the equaliser against Everton and he hit a stunning hat-trick against Norwich so, with the form that he is in and the way he can play the game, he is going to be the key player for Liverpool leading their attacking line.

"His movement, pace and energy will really unsettle a back four that has had to be chopped and changed of late. So Suarez really could cause Chelsea all sorts of problems.

"I am excited at the prospect of seeing Suarez at the weekend because when he is on form there is no better sight than seeing him torment defenders.

"For me the most important thing for Liverpool is for them to get bodies in the box to support Suarez. When I have seen Liverpool struggle to convert chances, they have had players isolated in those advanced areas and you can't afford to do that.

"With so many defenders absent, John Terry will be more important than ever for Chelsea.

"Over the last two months since things have turned around for Chelsea you just look at him and you see what a colossal figure he is.

"He is a phenomenal centre-half - an absolutely top-drawer centre-half. You can fault him for a number of issues but fundamentally as a player anybody would want John Terry in their team. He is that good."

The final represents the first of two trophy winning opportunities for Roberto Di Matteo's men, while Kenny Dalglish's side travel to the home of football hoping for their second piece of silverware of the season.

Having missed out on qualifying for the Champions League, The Reds can take solace from their double cup run, while Chelsea will have sympathy with their weekend opponents having had their own league campaign decimated by inconsistency.

Suarez and Terry are likely to be the main protagonists on Saturday teatime, however all eyes will be on Fernando Torres, who having scored a hat-trick of his own last weekend, will be looking to get one over his former side.
