Maddison is a really skilled midfielder and I think that he is good enough to play for even much bigger teams. This is why I think that Newcastle won't be the only team wishing to sign him in the summer. There should be some bigger teams in line to sign him also. Especially because of this, Newcastle had better finish this season in top 4. This will be making their side stronger to sign good players like Maddison. Because they will have something in their hands to offer them like the Champions League.
but it seems that in the transfer market this summer, James Maddison is likely to leave Leicester. that's because his contract is almost up and there is still no talk of extending the player's contract with the club. there will be quite a number of Premier League clubs interested in him.
There is an offer of 50 million as an initial offer but of course this cannot be done quickly because now with a lot of interest it is certain that Leicester will think of several options between holding back Maddison or letting go for a slightly higher price.
