The bad news for Newcastle United's rivals is that Alexander Isak is just getting started. Isak is becoming fitter, sharper and stronger and displaying the 'electric' attributes that have long excited staff behind the scenes in training.
You only have to look at the variety of Isak's goals in the last week, alone, to realise that. The Sweden international has scored three of Newcastle's last four goals in the Premier League to reignite the Magpies' Champions League push and each finish has showcased a different side to his game.
There was the typical striker's header against Wolves; the superb improvised volley at Nottingham Forest; and, finally, a nerveless penalty to win that game at the City Ground in the 93rd minute. It could yet prove a defining five days not only in Newcastle's season, but in Isak's career on Tyneside, too, as the record signing becomes the main man up top.
