LaLiga has seen a lot of upheaval over the past few months, none more so than since the start of August as Lionel Messi's future unravelled.

This will be the first season that LaLiga has been without Messi since 2003-04, and as such there are plenty of people suggesting Spain's top tier has subsequently lost much of its appeal.

Be that as it may, even with spending significantly limited among clubs this year, there are still some interesting new arrivals to LaLiga.

Below, Stats Perform uses Opta data to look at five of them…

Memphis Depay, forward - Barcelona, free transfer from Lyon

Granted, Barcelona's rocky financial situation means it is yet to be confirmed if Depay will be registered for the start of the season.

But assuming Depay is involved as Barca begin the campaign against Real Sociedad, he will be under pressure to help make up for the loss of Messi.

His record at Lyon at least shows he should carry a threat, and in theory he will be surrounded by better players at Camp Nou.

Depay scored 76 goals in 178 appearances for Lyon after joining from Manchester United in January 2017 and enjoyed a particularly impressive final season in Ligue 1, finishing with 20 goals to trail only Paris Saint-Germain star Kylian Mbappe (27).

The former PSV youth product's 12 assists and 94 chances created were more than any other player managed in France's top flight in 2020-21.

In all competitions, meanwhile, Depay scored 22 goals last term at an average of one goal every 141.5 minutes, making it his second-best season since arriving.

He massively exceeded his expected goals (xG) tally of 12.38, so perhaps he shouldn't be expected to be quite as prolific, but if he can reach double figures in goals and assists once again, Depay would have to be considered a shrewd signing.

David Alaba, centre-back - Real Madrid, free transfer from Bayern Munich

It has been a difficult few months for Madrid. While caught up in plenty of off-field controversy, they have also lost the centre-back partnership that guided them to so much success. Sergio Ramos and Raphael Varane, as well as their former head coach Zinedine Zidane, are no longer around.

The one signing Madrid have managed to bring in does at least offset one of those losses, as Alaba will offer experience, versatility and all-round quality at centre-back. After all, he made 298 Bundesliga appearances for Bayern, and a player does not reach such figures without being excellent.

He helped Bayern keep 111 clean sheets across those games, did not receive a single red card in the league, and made only two errors leading to goals in the competition, according to Opta data.

Bayern team-mate Thomas Muller is the only other player in Bundesliga history to have won 10 titles, and Bayern had counted on Alaba as their Mr Dependable. Carlo Ancelotti will hope he can form a great partnership with Eder Militao.

Rodrigo De Paul, central midfielder - Atletico Madrid, €35m from Udinese

While Diego Simeone has perhaps been a bit hit and miss when it comes to making the most of creative talents, De Paul appears to be ideal schemer for his new coach.

Providing creativity is De Paul's bread and butter, with his 82 key passes in 2020-21 bettered by only Hakan Calhanoglu (98) in Serie A.

Of those chances, 34 came from set-pieces, highlighting his prowess from dead-ball situations and ranking him fourth in Italy's top flight.

Only five players got more assists than his nine, but all of them massively out-performed their modest expected assists records, which ranged from 3.4 to 6.7. De Paul topped the charts for expected assists with 10.3 xA, evidence that his assists reflected the quality of his service rather than him getting lucky or benefiting from unusually good finishing by team-mates.

Yet the area which highlights a particular compatibility with Atleti is the fact he won more duels (294) than anyone else in Serie A in 2020-21.

Combine that with his league-leading completed dribbles (122) and it paints a picture of a hard-working player who also possesses the quality to get his team on the front foot.

Jose Macias, striker - Getafe, on loan (with purchase option) from Guadalajara

It is fair to say Getafe are not particularly one of LaLiga's most-fashionable sides. Under Jose Bordalas they were more renowned for their aggression and physical style of play, though new boss Michel has significantly different ideas.

In theory, that should immediately make them a more likable proposition for the neutral, and the signing of Macias will only add to the intrigue.

The 21-year-old Mexico international had been linked with numerous clubs with greater status than Getafe, such as Juventus, Borussia Dortmund and Sevilla, but Los Azulones pulled off something of a coup in bringing him to the Coliseum Alfonso Perez on loan with an option to buy.

Macias is the first forward that Guadalajara have sold to a European side since Javier Hernandez left for Manchester United in 2010 and he heads to Spain having netted 12 times in the most recent Mexican Apertura and Clausura campaigns.

His 20 shots on target in the 2021 Clausura was the most by a Mexican player, though it was during a loan spell with Leon where Macias really announced himself, netting 24 times in 38 Liga MX matches.

He didn't quite hit those heights again upon returning to Guadalajara, so the jury is still out to a degree, but there is lots of potential for Getafe to tap into.

Yusuf Demir, winger - Barcelona, €500k loan fee (€10m purchase option) from Rapid Vienna

Barcelona fans need not fear life without Messi, for they have signed the 'Austrian Messi'… or something like that.

Obviously that is a fair bit of pressure for an 18-year-old to have, particularly given he was initially signed for the B team, but he's produced some positive performances in pre-season for the senior side and arrived from Rapid with a burgeoning reputation.

While Demir only started in six of his 25 Austrian Bundesliga appearances (825 minutes) last season, he finished the campaign with a highly respectable seven goal involvements, which averages out at one every 117.9 minutes – only 10 players to play at least 825 minutes had a better record.

Despite only getting the one assist, Demir was a regular source of creativity when he did feature, as highlighted by the fact his 2.7 key passes per 90 was the sixth highest among those to play at least 825 minutes.

But arguably his most notable asset, and the one that inspires the comparison with Messi, is his ability on the ball.

A dynamic and exciting player, Demir attempted 6.3 dribbles per 90 minutes on average, a figure matched by no one who featured for more than 108 minutes last term.

Similarly, he was successful with 3.8 dribble attempts per game, which was also a league high. It was that kind of flair that helped him realise a childhood dream by moving to Camp Nou, and he could have a more prominent role than he may have initially predicted upon his arrival.
