The Liverpool manager saw six of his players booked - there were nine cautions in all during the 1-1 draw - and skipper Steven Gerrard come close to being sent off for a shove in the face of Feyenoord's Theo Lucius as the game deteriorated into a melee involving most of the players on the pitch.

Gerrard had earlier grabbed Liverpool's equaliser but was furious with a late tackle from young winger Royston Drenthe, the hosts' first-half scorer.

Lucius had earlier twice pushed Daniel Agger as tempers flared.

Benitez said: "I do not think Steven will be in trouble, there was a lot going on out on the pitch.

"It was hard to see what was going on and I would want to review the match before commenting.

"But I would need to see the replay to decide what happened, but maybe you should talk about everything with the referee.

"I felt the team played okay, we had some chances but could not score. In terms of football, we were all right. As for the tournament, this was a very strange one."

Benitez was clearly not impressed by the standard of the event that included a very poor Shanghai side and a competitive but defensive host club.

He added: "Maybe these kind of games are more difficult with a local referee in charge. They become even more difficult.

"I am not bothered really about what went on and how the lads were treated, it is not the end of the world."

And Benitez praised Gerrard's contribution and goal, coming after his excellent effort in Friday's 2-0 win over Shanghai.

Benitez said: "Steven showed us what he can do, there was another goal for him. But the team also, they created chances and played well.

"Steven though will normally play more games this season in a central role. We have got plenty of wingers now.

"We have confidence, we have prepared well and have a better squad than last season, so hopefully we can start with a win in the league at Aston Villa on Saturday."

Liverpool started with poise, control and dominance. But they could not turn possession into goals.

Gerrard had a volley over and saw another effort glide wide after a surge into the box, while John Arne Riise was also wide with a drive.

On 15 minutes, Dirk Kuyt, back in front of the Feyenoord fans he served so well before his move to Anfield, saw a fierce drive crash against the bar, giving Egyptian keeper Sheriff Ekramy no chance.

It bounced down, seemingly over the line, but with no official near enough to award the goal play went on.

And a minute from the break Liverpool's wastefulness was punished when Andwele Slory got in behind Riise on the right and saw his shot cannon back off a post for Drenthe to score.

The flying winger, a key member of Holland's European Under-21 Championships title winners this summer, gave Liverpool plenty of problems, Arbeloa being booked for one desperate tug on the youngster.

Liverpool's frustrations boiled over after the break with both Kewell and Jermaine Pennant also booked.

Not surprisingly, Kewell was replaced by Ryan Babel soon after. Pennant was next off on 64 minutes, Fernando Torres taking over.

And with Liverpool looking laboured and short of ideas against a deep defence, it was Gerrard who came to the rescue on 72 minutes.

He strode past two men on the right of the box and drilled an angled shot past Ekramy.

Babel and Xabi Alonso both had good efforts wide before Yossi Benayoun replaced Voronin.

But Feyenoord continued to be competitive, and it was Gerrard who had to kick off the line from Hofs, before Alonso and Drenthe were booked for squaring up.

Javier Mascherano soon replaced the Spanish midfielder.

There was more drama when Feyenoord were awarded a penalty for a supposed hand-ball against Arbeloa, the ball in fact striking his head following a Drenthe cross.

But Reina's famed penalty-saving ability saw him turn away Danny Buijs' effort.

But worse was to follow when Drenthe caught Gerrard with a late tackle.

All hell broke loose, and Gerrard was booked for pushing Theo Lucius in the fracas.

He was instantly withdrawn with Mohamed Sissoko coming on in the final seconds.
