Kevin Grosskreutz has returned to Germany with Stuttgart without making a single appearance for Galatasaray. He's not the only one to leave before he's even started, though, as FFT's Chris Flanagan attests...
1) No goals in pre-season? You're sold!
English football's first £1m signing Trevor Francis scored the winning goal in the 1979 European Cup Final for Nottingham Forest, but the first teenage seven-figure signing made much less of an impact at his new club.
Clive Allen was 19 when Arsenal boss Terry Neill spent £1.25m to sign him from QPR in the summer of 1980. He'd scored 32 goals in 49 appearances for Rangers, but after none in three pre-season games for his new club the young striker was moved on to Crystal Palace in a swap deal with Kenny Sansom and Paul Barron.
There were suggestions that the Gunners had wanted Sansom all along, and this had been their plan to get him, but Allen wasn't convinced. "Several different theories were put forward," he said. "There was no foundation to any of them. I mean, if Arsenal wanted Kenny, why didn't they just buy him from Palace?"
2) 'The English, what have they won?'
Stephane Guivarc'h shot to fame as the striker who somehow couldn't score in the France team that was busy winning the 1998 World Cup.
Those were presumably the credentials that Newcastle thought would be perfect for them when they signed Guivarc'h shortly afterwards. Perhaps they hoped the frontman and his knack of failing to score would turn the rest of the Newcastle team into Zidane, Djorkaeff and Henry.

Unfortunately, though, it didn't quite work out that way. He did net on his debut against Liverpool but made only four appearances before Ruud Gullit, in as manager for Kenny Dalglish, sold him to Rangers for £3.5m.
He was later named as one of the Premier League's worst ever strikers in a national newspaper survey, to which Guivarc'h later retorted: "This survey, I don't give a damn about it. It was done just to tease and mock me. What a story - a truly pointless stunt. But let's get to the point. The English. What have they won since the World Cup in 1966?" Charming.
3) Bebe steps
Portuguese forward Bebe was happy enough when Europa League regulars Vitoria Guimaraes signed him on a free transfer from cash-strapped Estrela da Amadora in 2010. So he presumably couldn't believe his luck a few weeks later when, before he'd even played a game for Vitoria, Manchester United made their move... for £7.4m. Bebe certainly must have been something special in pre-season – so much so that Vitoria had swiftly increased his previous buyout clause of €3m.
But that form swiftly evaporated and he made only seven appearances for United, spending time on loan at Besiktas, Rio Ave and Paços de Ferreira before joining the former permanently in July 2014. After playing once for the Eagles he was shipped off on loan again to Cordoba, then Rayo Vallecano for the 2015/16 campaign. Perhaps he just doesn't like the cold.
