Two of the world's most famous derbies -- Rangers-Celtic and Everton-Liverpool -- take place on Saturday. Lionel Messi hopes to continue his scoring streak for Barcelona, which travels to Villarreal. Bolton has given Arsenal all kinds of trouble in recent years, but it was hit this week by a managerial crisis.

MATCH/EVERTON-LIVERPOOL
Liverpool is hoping the 177th Merseyside derby will jumpstart its season.

Three straight ties have dropped the Reds six points behind leader Arsenal in the English Premier League, and they are in trouble in the Champions League after losing at home to Marseille.

"We are not playing well and we have not played well in the past two or three games," said Liverpool manager Rafael Benitez. "This is the kind of game that can change everything. It is a derby and we can play well and win and everything will be different."

PLAYER/LIONEL MESSI
Lionel Messi is expected to lead Barcelona, which takes a four-game winning streak into Saturday's game at Villarreal.

Messi has scored in every game of the winning streak and also scored in Argentina's 2-0 win over Venezuela in World Cup 2010 qualifying on Tuesday.

With Samuel Eto'o sidelined and Ronaldinho being rested after playing for Brazil in World Cup qualifying on Wednesday, Messi, La Liga's top scorer with six goals, and Thierry Henry will have to carry the Barca attack against Villarreal.

COACH/ARCHIE KNOX
Archie Cox is expected to hold on to his role as Bolton's caretaker manager through Sunday's match at English Premier League leader Arsenal.

Cox was named interim boss following the dismissal of Sammy Lee on Wednesday only five months after taking over from Sam Allardyce. Cox is on a shortlist that is believed to include former Fulham manager Chris Coleman, now at Spanish club Real Sociedad, former Wigan manager Paul Jewell.

Bolton has a history of success against Arsenal. It's won three games, tied two and lost only once in their last six EPL meetings, and it knocked the Gunners out of the 2006 FA Cup and forced them to a replay in 2007.

RACE/SCOTTISH PREMIER LEAGUE
Both Rangers and Celtic must regroup following a week of international action for their Scottish Premier League showdown on Saturday at Ibrox.

DaMarcus Beasley, who went off a half hour into the USA's 1-0 win at Switzerland on Wednesday with an ankle injury, is one of three Rangers to pick up injuries while on international duty. Beasley is doubtful to play his first Old Firm match, but Scotsmen Allan McGregor and Alan Hutton could be fit for Saturday's game.

Celtic goes into the game with a one-point lead on Hibernian and a three-point lead on Rangers. Celtic manager Gordon Strachan bemoaned the loss of key players for the last week. "We are only together for a couple of hours before a huge game of football," he said.
