Jose Gomes admits he is unsure what system Rovers will play at Reading, but is certain who their main threat is.

The Royals boss has pinpointed Bradley Dack, who has two goals in his last two matches, as the key man to watch.

Tony Mowbray switched to a back three against Millwall, a system Reading have regularly deployed this season, but whatever formation Rovers go with, Gomes knows what kind of team are arriving at the Madejski Stadium.

He said: “They have a very good dynamic. Blackburn are playing very well, mixing youth energy with quality experienced players.

“Dack, definitely, is the player who is linking all of their game. He’s trying to receive between lines and linking with the forward players, and there’s a very good dynamic with the full-backs.

“They played six games with one formation and then in one game they changed it. We have this doubt, but their dynamic is basically the same.

“We just need to keep our focus and do the things we can do properly.

Reading have taken seven points from their seven matches so far, but could move level with Rovers should they come out on top in tomorrow afternoon.

Despite the mixed results, Gomes is taking a positive approach in to the game and feels his side can cause problems.

He told his club's website: “We need to be optimists and believe and trust in the process.

“The way that my players have been working, if we keep this spirit, it will be very, very difficult to beat us.

“There’s a very good atmosphere in the changing room, a very good relationship between all of them. We must feel hope in this group because they will give a lot of victories.

“I really believe that if we win the next game, we will have a long period of victories in front of us. We were better against Middlesbrough in all the data - number of shots, ball possession, number of passes, forward passes, the defensive challenge, we were better in all of those areas.

“But it’s football. We didn’t score, we created a lot of situations where we could, but we didn’t. We must keep the positive things in our hands, help the players to be better and show them that we trust them.

“We really believe that they will give to us a lot of fantastic things in the future.”
