Trent Alexander-Arnold’s Real Madrid career has not got off the ground yet, but fit again after injury, the England right-back could be crucial for the Spanish giants in the second half of the season.

With Alvaro Arbeloa’s side still taking shape following the coach’s arrival in January, Alexander-Arnold has the chance to make himself a key part of the club’s battle for silverware.

Pellegrino Matarazzo’s in-form Real Sociedad visit the Santiago Bernabeu on Saturday in La Liga, in what promises to be an enticing clash.

Arbeloa’s Madrid are looking to move two points clear of Barcelona and take the lead in La Liga before the Catalans visit Girona on Monday.

Al Jazeera Sport takes a look at Saturday’s headline fixture in La Liga.

Will Alexander Arnold start for Real Madrid against Sociedad?

Former Liverpool full-back Alexander-Arnold, who came off the bench last weekend as Madrid beat Valencia, could potentially start for the first time since December 3.

After a decent early showing for Madrid at the Club World Cup last year, hamstring and thigh injuries have stopped him from settling in, limiting him to 12 appearances across all competitions this season.

“After [he’s had] a long time out, we will proceed with caution,” said Arbeloa after Alexander-Arnold’s return, with Spanish newspaper AS reporting Madrid’s aim is for him to start against Benfica in the Champions League playoff round on February 17.

Even if Arbeloa uses veteran Dani Carvajal or youngster David Jimenez to start against Real Sociedad, the expectation is for Alexander-Arnold to get more crucial minutes under his belt.

How are Real Sociedad faring in La Liga this season?

Real Sociedad are unbeaten in nine matches but are eighth in the table – 14 points off fourth place and the crucial UEFA Champions League qualification spots.

Matarazzo’s side did, however, defeat champions Barcelona last month and have one foot in the Copa del Rey final after a semifinal first leg win at rivals Athletic Bilbao this week.

Sociedad are also coming off a 1-0 win at Basque Country rival Athletic Bilbao in the first leg of the Copa del Rey semifinals.

Will Vinicius and Mbappe’s dinner give Madrid food for thought?

Real Madrid is counting on a team-bonding dinner reportedly paid for by its biggest stars to boost its late-season pursuit of the La Liga and Champions League trophies.

Vinicius Junior and Kylian Mbappe paid the bill at the restaurant in Madrid on Tuesday, midfielder Dani Ceballos told reporters. The tab ran in excess of 1,000 euros ($1,100), according to accounts by Spanish media.

Vinicius posted a photo of the entire squad during the dinner near the city centre in a fancy location that features an “Art Dining Club.”

Fans waited outside the restaurant to try to talk to the players after the dinner, which went well past midnight.

Coach Alvaro Arbeloa and his assistants were not part of the dinner, Spanish media said.

The show of unity came a week before Madrid faces Benfica in the first leg of the knockout playoffs of the Champions League. The team dropped out of the top eight that automatically qualified for the round of 16 after a 4-2 loss at the same as Benfica in the final round of the league phase.

Defender Raul Asencio told media that after the dinner, the team was “very united.”

Why has Real Madrid struggled this season?

Madrid went through turmoil at the end of last year, with some players reportedly not on the same page with coach Xabi Alonso.

Under Arbeloa, Madrid was eliminated by second-tier Albacete in the Copa del Rey round of 16, and lost to Benfica in the match that relegated the team to the Champions League’s knockout playoffs.

With the bad-tempered Bernabeu crowd on their own team’s backs in recent weeks, the chance to move top of the table could settle the natives.

How is the La Liga race shaping up for Real Madrid and Barcelona?

Madrid has won seven in a row to be one point behind leader Barcelona.

Barcelona will look to win its fourth in a row in the league against a Girona that was in 12th place and was winless in its last three matches.

Barcelona is coming off a resounding 4-0 loss to Atletico Madrid in the first leg of the Copa del Rey on Thursday, when it conceded all goals in a disastrous first half.

It had won 17 of its last 18 matches in all competitions before the defeat. The last setback had been losing 2-1 at Sociedad in the league last month.

Third-placed Atletico will face lowly Rayo Vallecano on Sunday, while fourth-placed Villarreal is at mid-table Getafe.

What happened the last time Real Madrid met Sociedad?

Los Blancos were 2-1 winners against Sociedad in September’s reverse fixture in La Liga.

Kylian Mbappe and Arda Guler scored either side of Dean Huijsen’s sending off in the first half.

Mikel Oyarzabal’s 56th-minute penalty offered the home side hope, but they were unable to further make the most of their numerical advantage.

Head-to-head

This is the 184th meeting between the teams, with Madrid winning on 103 occasions and Sociedad claiming the spoils in 38 of the contests.

The first fixture was played in April 1905, with Madrid winning the Copa del Rey meeting 3-0.

He had already been held to gym work on Wednesday. The club did not immediately give any details about his condition.

Vinicius was set to be back with Madrid after missing the previous league game because of a yellow card suspension, but Jude Bellingham will remain sidelined with a hamstring injury.
