Fulham head coach Alvaro Arbeloa criticised his team's attitude, commitment and desire after defeat by Sunderland, whose first Premier League win of the season came courtesy of substitute Wilson Isidor's strike.

Isidor came on in the 64th minute and made a decisive impact in a scrappy game of few clear-cut chances.

He nearly scored when found unmarked in a central position in the penalty area, only to hit the foot of the left post after the opportunity had been created by Granit Xhaka and Enzo le Fee.

Isidor, who got a goal for Haiti during the summer's World Cup, then made it 1-0 in the 75th minute.

The breakthrough came when fellow substitute Habib Diarra did superbly with a rapid run down the right wing and Fulham goalkeeper Bernd Leno could not gather his low cross, with Isidor able to convert to put the Black Cats ahead.

A furious Arbeloa, after only his third competitive match in charge of Fulham, said he "didn't like the attitude of my team" and added: "We didn't even fight, we didn't run, poor technical level. We were not in the game."

Fulham were beaten 3-2 by Chelsea on the first weekend of the season, in a thrilling game.

"Against Chelsea at home, it's easy to run and fight but you have to do it every game," said Arbeloa.

"It's about the character, the mentality, and ambition. We didn't win any second balls. We want to be competitive, it's the most important thing for a team. We were not at our level - we need to show something more."

Fulham put in a disappointing performance and could not break through an organised and hard-working Sunderland defence, failing to produce a shot on target.

It means the Cottagers have lost both of their Premier League matches so far.

The first half lacked quality, with both sides guilty of wasting good positions with poor final passes or lack of composure in front of goal.

Sunderland created a good chance in only the fifth minute when Xhaka spread play with a pass out wide and Thomas Meunier put a cross into the penalty area, only for Trai Hume to fail to connect with the ball from 10 yards out.

The Black Cats finished seventh in the Premier League last season, to earn a first shot at a European competition since 1973-74, when they went out of the Cup Winners' Cup in the second round.

Despite conceding a last-minute goal to lose 2-1 at promoted Ipswich in their opener, with former Sunderland winger Jack Clarke scoring the winner, Friday's Europa League draw lifted the mood.

A dream away tie at Italian giants AC Milan on 10 December is something for Sunderland fans to relish, with home games against Dutch outfit AZ Alkmaar, Dinamo Zagreb of Croatia, Polish side Jagiellonia and Levski Sofia of Bulgaria, along with further trips to Portugal (Torreense), Poland (Lech Poznan) and Belgium (Anderlecht).

But one of the big questions for Sunderland fans is how their squad will cope when they have a minimum of eight extra fixtures and regularly have to play on Thursday and then Sunday.

After losing at Ipswich, it was important the Black Cats picked up three points here and they managed to do that, with Xhaka the outstanding player with his long-range passing and inspirational leadership.

At Portman Road, individual mistakes had proved costly, but boss Regis le Bris had reason to be delighted by the team effort against Fulham and the way his side defended.

Nordi Mukiele and Romaine Mundle typified that resolute spirit with last-ditch blocks to help shut out Fulham.

"It's good to be back at home and win again," said Le Bris.

"The Premier League is really demanding and we faced a really good team. The lads did really well to manage their threat and create opportunities up the other side."

Former Real Madrid boss Arbeloa took over at Fulham after Marco Silva's June departure, and his side scored five goals in their first two competitive matches.

After the defeat by Chelsea and then a 3-0 win in the Carabao Cup against League One side AFC Wimbledon, this time the goals did not flow.

Arbeloa, his players and Fulham's fans will all have been left frustrated. Despite having 58.4% of possession, the Cottagers frequently got into promising positions and were let down by a final pass or lack of composure in front of goal.

Their best chance dropped to Josh King when the game was goalless. Unmarked when played in by Alex Iwobi, King could only shoot wastefully over.

Striker Gonzalo Garcia joined from Real Madrid in early August and scored in both of Fulham's first two matches, but he was among those to disappoint on Wearside.

He failed to test home goalkeeper Robin Roefs, with Garcia's best two chances being charged down by firstly Mukiele and then Mundle.

Fulham beat Sunderland home and away last season but now have no points from two games. They will be looking to get their first league win next Saturday at home against Crystal Palace, another side with two defeats from two matches.

The transfer window closes on Tuesday and the lack of threat up front may convince Arbeloa that his side need further attacking options if they are to match or improve upon last season's 11th-placed finish.
