This summer, Premier League fans will clamour again for new signings to spark their beloved clubs back into life. But they should be careful what they wish for, as not all transfers have happy endings. Indeed, there are few guaranteed successes ... although Erling Haaland might be the nearest thing.
Haaland, 20, has hit 49 goals in 52 games for Borussia Dortmund since his January arrival last season and is the prime target for several of Europe's top clubs this summer, though you wonder who can really afford him after reports that his agent Mino Raiola is seeking football's first £1 million-per-week pay packet.
