Rangers have responded after Porto tabled a transfer bid of around £10.3m for Alfredo Morelos, according to journalist Ekrem Konur.
Morelos hasn’t yet linked up with the Rangers squad for pre-season as he’s still taking part in the Copa America with Colombia.

La Tricolor were defeated by Argentina in the semi-final overnight but still have the third-place playoff to come.
The Gers striker may have been on international duty for some time, but there’s been plenty of speculation about his club future.
Outlets in Portugal have been linking him with Porto for weeks [A Bola] and on Saturday, journalist Ekrem Konur asserted on Twitter that the Portuguese giants had offered Rangers €12m (£10.3m) plus a 20% stake in Morelos’ next sale.

Konur then issued an update on Tuesday evening, claiming that the Gers had rejected the bid.
He goes on to assert that a lot of teams are keen on El Bufalo but that Rangers are in no hurry to sell him.
Rangers fans will no doubt be delighted with this update for a number of reasons.
Firstly, most Bears will want Morelos to stay for at least another season as the club bid to defend their Premiership title and qualify for the group stages of the Champions League.

By the same token, most supporters would begrudgingly accept him moving on in this window but only if a significant fee was received by the club.
Rangers have previously valued the Colombian at £20m [Scottish Sun] and reportedly turned down a bid of £16.25m from Lille last summer [Daily Mail], so there would have been uproar if an offer in the region of £10m had been accepted here.
Bears will also be pleased with a move made by Castore earlier this week following fan requests.
