As Celtic prepare to fight it out with Malmo of Sweden for a place in the lucrative group-stages of the Champions League, the latest name linked with the club is Swansea City's Spanish striker Michu.
Manager, Deila, is keen to add more firepower to his Celtic side if they make it through the play-off tie and sees the forgotten forward as the right fit.
Michu was a sensation in his first season under Michael Laudrup after the Dane paid a modest £2 million for his services from Rayo Valleycano back in 2012. However, his second season was marred by injury, and then Laudrup was relieved of his duties as manager shortly afterwards.

This apparantly did not sit well with the towering striker and he took the matter up personally with the powers that be in South Wales.
Poor form and injuries
This lead to 29-year-old Michu being farmed out on loan to Napoli just last year, a move that did not work out so well for him as he once again struggled in Italy with niggling injuries. During his time in Naples, the loanee managed just three appearances.
Celtic are on the look-out for a centre-forward who can play as a loan striker, as Deila prefers a 4-2-3-1 system. The club have recently added Nadir Ciftci to their ranks, whilst Leigh Griffiths has been on form in the Scottish Premership - his most goal recent coming against Inverness at the weekend.
The club also have Anthony Stokes and last summer's £2.3 million signing, Stefan Scepovic on the books, although Stokes has been told he is surplus to requirements at Parkead and the latter has struggled for form since arriving in 2014.
If Celtic do make it to compete with Europes elite, Stokes and possibly even Scepovic will be on the move, which could open up the door for Michu.
Any move for the man who at one time was linked with a £25 million move away from the Welsh side would almost certainly be a loan deal just like before.
The Spanish international is heading into his last year in what was a mamoth £40,000 a-week contract, and with Celtic sticking rigidly to the wage-structure they have in place, a permanent agreement could be a long way off.
Meanwhile, Celtic have had bid, believed to be around £4 million, rejected by Dinamo Zagreb for Croatian under-21 international, Jozo Simunovic - as per the Daily Record.
Chief Executive, Peter Lawell, flew to Zagreb for negotiations but it appears as though the Croats are playing hardball over the man who is viewed as Virgil Van Dijks replacement.
