Indeed he is. Last summer's transfer business was brilliant but Xhaka has stood out as the most important signing bar none. It is very fortunate for you but terrible news for us that you've not only finally appointed an outstanding manager but a man who played such a pivotal role in Xhaka's career. If it wasn't the double attraction of Alonso and London I think Xhaka would have been more than content to stay another year or two on Wearside. However if he is to leave then £20,000,000 is not an unreasonable fee. Conveniently what Chelsea have just pocketed while upgrading from Maresca to Alonso. Xhaka is 33; Thiago Silva was weeks short of his 36th birthday when he signed for Chelsea. I'd presume, with hindsight, few Chelsea supporters would think £20,000,000 wouldn't have been a bargain for him. I believe 2026-7 will be a very enjoyable and memorable one for Chelsea providing Alonso is given the signings he wants. Looking from afar I'd think a top striker would be near the top of his list. But right at the top and the foundation of your side for next season is Granit Xhaka. There isn't a single Sunderland supporter who won't be sorry to lose him whatever the fee. But if he's to go then I hope at least that your ridiculously profligate owners aren't going to be parsimonious just when the player in question will be worth a lot more than a third of a Mudryk.
