England is far away, very cold
The geographical distance is the first " front line" in a series of reasons why Barca should not play in the Premier League. Catalan is 912 miles from London by air.
If they have to fly to England every week, Barca players will spend the whole day just sitting on a plane, affecting each player's health. Not to mention that if they participate in other tournaments such as the FA Cup, League Cup..., Barca will have to travel more than that.
In addition to geography, the British climate is an unlikely factor to adapt to for Catalan people who have long been accustomed to the sunny and windy region of the Iberia peninsula. If they go to England, they face a day of dense fog and humid rain all year round. In addition, winter in England is extremely cold.
The English league has no winter break, the prospect of having to work hard on the pitch when it is snowing, are you sure Messi and his teammates will accept it?
Premier League has many "leading and fighting" players
In La Liga, Barca only think about competing with Real all year round. In recent years, Atletico has been added but the impact is not too significant.
But for England, that race with Barca is no longer a "song" but will become a "four card", "song card"..., is Barca sure that any match against M.U, Man City, Chelsea, Liverpool... can also win all 3 points?
In addition to the above big teams, the sudden rise of mid- and high-level clubs in the Premier League in recent years has caused a lot of change in the situation of this tournament, typically the championship of Leicester in the 2015-16 season. In the Premier League, Liverpool's 4-0 win over Arsenal but then losing to Leicester was a " profit".
In front of Barca, there will be the prospect of having a host of "giants" plus a series of "hammocks" always ready to "pick up the wheel". The championship race is no longer as relaxed as in Spain. It is not known that if a bad situation occurs, Messi sitting at home watching the Champions League will also be a possibility.
No club in England wants to " feed" Barca
Television copyright is a very important factor for English clubs because their tournaments are always associated with the word "money".
Barca will play England, it is inevitable that they will be placed in the Premier League. So, who will give Barca a place when the tournament has only 20 teams? A Premier League team, just needing to be promoted from the Championship, has up to 98 million pounds in television rights. If Barca comes, a promotion spot will also be lost in that first year and will the team that suffered the consequences in the Championship accept it?
And with their reputation, Barca will be given more TV rights, other big clubs will be cut in half for that fat "piece". When touched with a "piece of rice", no one will welcome Barca.
