Iwan Roberts reckons a testing run of fixtures could scupper Swansea City's play-off chances despite their "really big win" at Portsmouth.
Swansea are within five points of the Championship's top six after claiming just a fifth away triumph of the season at Fratton Park.
Vitor Matos' team go to Wrexham, who currently occupy the final play-off spot, on Friday (20:00 GMT).
Former Wales striker Roberts believes that game is tough to call given Swansea's good form and Wrexham's midweek home loss to Hull City – but says Matos’ men face a succession of stern challenges in the next month.
"Before the game last Saturday, I think Swansea were 11 points from the bottom three and I said they were still looking over their shoulders," Roberts told this week's Feast of Football podcast.
"All of a sudden they win two games and we are talking about them getting into the top six. It shows how quickly the Championship can change.
"But have you seen their games? After Wrexham, [they have] Coventry at home, Sheffield United away, Middlesbrough at home in the next three. They have some tough games coming up."
Swansea head to north Wales having won six of their past 10 games, with Matos inspiring an upturn in fortunes since taking the reins in November.
The majority of their recent successes have come on home soil, making the 2-1 triumph at Portsmouth all the more satisfying.
"They were going to Fratton Park, a tough place where you have to fight and scrap and roll your sleeves up, I didn't see that result coming when you think they'd lost nine of their previous 11 away games," Roberts added.
"It was a big win, a really big win. I don't think they have won three in a row since last April but they have a chance now of doing that on Friday night."
