Isak needs time to bed in at Liverpool 

After missing pre-season through protest, Alexander Isak got his way and made the move to Liverpool. The Premier League champions paid a record sum to acquire the striker but it may take time for him to get up to speed. The Sweden international did not feature against Slovenia for his national team, spending the match as an unused substitute, but he did come on in the 2-0 loss in Kosovo, making it an underwhelming start to the season for Isak. Liverpool have plenty of matches to ease Isak into his new surroundings and are helped by being the only team with a perfect start to the campaign, with three wins in as many games. Starting at Turf Moor looks unlikely for Isak but coming off the bench is almost a certainty. Patience may be required before Liverpool see the same effectiveness he brought to Newcastle, however.
