Manchester United striker Robin van Persie played for the Red Devils today – but rumours persist that all is not well between the Netherlands international and his current employers.
It's possible that the rumours are true – and who could blame Van Persie for feeling a little edgy after such a poor start to the season?
Anyway, Van Persie will be 31 next season and United will need to start planning for the future.
So which striker should they consider purchasing as his long-term replacement?
5. Giuseppe Rossi | Fiorentina
How about replacing one prolific left-footed striker for another?
Giuseppe Rossi grew up at Manchester United before being sold to Villarreal in 2007, despite the fact that he was considered the most natural finisher at the club since Ole Gunnar Solskjaer.
The Italy international has since proved his credentials in Spain and now Italy, where he currently leads the Serie A top scorer charts with Fiorentina.
4. Diego Costa | Atlético Madrid
Diego Costa is a defender's nightmare: he works tirelessly for his team, he's aggressive, sometimes downright dirty, and he scores goals.
The similarities with Luis Suarez are obvious – and how United could do with someone like him right now.
3. Radamel Falcao | AS Monaco
Rumours suggest that Radamel Falcao is unhappy at AS Monaco – which is no real surprise considering the club's average gate is a pitiful 8,000.
The Colombia international deserves to be playing in front of crowds of 70,000+ every week – and he could do just that at Old Trafford.
However, United would need to pay a fortune for the Chelsea target, with reports claiming that Monaco want at least £80m for the prolific South American.
2. Wayne Rooney | Manchester United
Wayne Rooney is, of course, already a Manchester United player. But it's been a little while since he played as an out-and-out striker for the Red Devils.
In recent weeks, with Robin van Persie out injured, he has played as United's most advanced player – and, naturally, he's performed very well.
Is Rooney more dangerous as a No. 10 or a No. 9? It's something for David Moyes to consider.
1. Robert Lewandowski | Borussia Dortmund
If Moyes decides that Rooney produces his best football as a No. 10, then Robert Lewandowski would be the best possible Robin van Persie replacement.
The Poland international is an excellent striker who can hold the ball up, bring others into play, score goals – he can do the lot.
He looks set to join Bayern Munich in the summer, but could United strike a deal in January?
