The IPL (Indian Premier League) was a great success. It attracted lots of spectators and players were paid a great deal of money for participating. Most of the best cricketers played in it.
The leagues in England do not attract as many spectators and the players are not paid as much as the players in the IPL are paid. At the moment they have a Twenty20 league and a Pro 40 league.
International players already play a lot of cricket so sometimes they can get tired and even get injured. Sometimes players can be rested for international duty. Adding lots of cricket leagues might not be too good for international players but it will be really good for spectators. As well as that players will earn a lot of money. There are many positives and negatives regarding this but I think more people would profit if a similar league to the IPL in England was made.
