Scott McDonald's second goal in Celtic's win overnight could be worth £10 million. When McDonald weaved and bobbed his way through the Kilmarnock defence to give Celtic the win, it also put them back on top of the Scottish Premier League table and three points clear of Rangers who faltered to the lowly Inverness Caledonian Thistle.

If Celtic can hold on to that top position with 10 matches remaining and again qualify for the UEFA Champions League, it is worth a minimum of £10 million to the club and McDonald, who has already proved his worth to the Hoops, will only become more valuable.
