Alexis Mac Allister and Dominik Szoboszlai will bring "energy and quality" to Liverpool, says former Reds midfielder Lucas Leiva.

Liverpool is hoping to bounce back from a disappointing season that saw them fail to win a major trophy for only the second time in five campaigns, while they also failed to qualify for the Champions League.

It has looked to freshen up its midfield in this transfer window, with Mac Allister and Szoboszlai for sizeable fees from Brighton and Hove Albion and RB Leipzig respectively.

Naby Keita and James Milner left on free transfers at the end of last season, though the departure of captain Jordan Henderson, and the impending sale of Fabinho, both to Saudi Pro League clubs, have perhaps left Liverpool with more work to do than they initially planned.

Lucas believes Mac Allister and Szoboszlai will bring an exciting new dimension to Liverpool, who have been known for their workmanlike midfield in their hugely successful recent period under Jurgen Klopp.

"I think they bring energy, a lot of energy and quality," Lucas said. "Things that to play for a club like Liverpool you must have.

"A lot of players departed so it was important to replace these players, especially in midfield where it's an area of the team that is very demanding. Jurgen asks a lot from the midfield players.

"These players for sure bring a lot of energy and I'm looking forward to watching them too, for sure."

Despite the potential for nerves at joining such a big club, Lucas feels Mac Allister and Szoboszlai will hit the ground running at Anfield.

"When you change a club or you move, of course there is a time that you need to adapt," Lucas explained. "But I think in the preseason, that's why starting from the first day is really important and they did that.

"I think the structure of the team as well with a lot of experienced players, I think they will help them.

"It's really important now in the preseason that they take part of the preseason, the full preseason, so they will understand the way the team and Jurgen wants to play, and I'm looking forward to seeing these two players, especially because they are young and very promising."

Lucas was only 20 when he joined Liverpool. The midfielder explained he struggled initially before going on to make 247 Premier League appearances and becoming an Anfield favourite over a 10-year spell with the club. 

He believes that the previous experience of Mac Allister and Szoboszlai playing in Europe's top five leagues will give them an easier start than the one he had.

"Well my first seasons for Liverpool to be honest, were very difficult," Lucas added. "I was very young, I was only 20 and I left Brazil straight to go to the Premier League, so I took a bit of time to adapt.

"But these players that arrived, I think it's different. Mac Allister, he already knows the league. I think it will be it will be easier for him. So that's very important.

"[Szoboszlai] has got experience as well, he played at a great club in Germany. So I think it's a bit different than when I joined Liverpool. I think the team is more robust I would say."
